If you're a college student with an Amazon Prime subscription (which you should be because it's crazy cheap for students), you'll know all about Amazon instant video. It's like Netflix, but for Prime subscribers, which seems kind of worthless if you're also paying $8 a month and practically live on the Netflix tab in your browser like I do, but there is an amazing show on Amazon that you won't find anywhere else.

"Orphan Black" is about a girl named Sarah Manning who is nine parts hot mess and one part utter disaster when we first meet her. Her life is coming apart as always, and then she watches as a woman—Beth Childs—who looks just like her steps out in front of a train and kills herself. Desperate for money to prove she can support her daughter Kira, Sarah takes the dead woman's purse. She finds her keys, goes to her apartment, and hatches a brilliant plan to get rich quick. Sarah assumes Beth's identity to get her money out of the bank, and it all seems to be going just fine until she's dragged to a police station and finds out Beth Childs is a cop. She's also getting some pretty weird calls and texts from one of Beth's two phones she left behind. This all leads up to her meeting yet another woman—Alison Hendrix—who again looks just like her. That's when she joins Clone Club. Because that's what they all are. Clones. And now it's time to figure out not just who created them all, but who's trying to kill them off. Oh yeah, that's another small detail. They're all being killed off.

Meet some of the clones and their closest allies.

1. Sarah Manning

Sarah thinks she's just your ordinary, run-of-the-mill screw up. Her ultimate goal is to find a way to prove she can care for her daughter...and then to do just that. That's why, when she sees a woman set down her purse before committing suicide, her first thought is to take the purse and go. Her life gets a little more complicated when she finds out she's a clone, but her top priority is always her daughter Kira.

2. Beth Childs

There's not much time to get to know Beth, what with her dying just a few minutes into the pilot episode, but luckily the first episode of Season 4 is a trip back in time to get a glimpse of who she was. Most of what is known about Beth prior to that was given in how Sarah acted when she stole her clone's identity and lived her life for the beginning of Season 1. Beth is a detective, addicted to pills and trying her very best to figure out what the deal is with her whole life-as-a-clone situation.

3. Alison Hendrix

Alison Hendrix: soccer mom. The title could not fit anyone better, as in her first appearance she is quite literally taking her kids to soccer practice. My biggest regret was not being Alison's biggest fan from the start. With Beth gone, she's the clone most skilled with a gun (although the others do learn fast), and she's the financial backing of Clone Club, which she feels is the best she can do while being at home with her nice family and suburban life. But oh Alison, you are so much more, including school trustee. And also drug dealer. Briefly.

4. Cosima Niehaus

The brains of the operation. Cosima's probably pretty close to genius. She's a Ph.D student and a key member of Clone Club. What's not to love about Cosima? Once she went to a fancy lecture at school and stole two bottles of wine. Sometimes she uncovers vital information regarding the clones' genome sequences. Occasionally, she makes the mistake of falling in love with her monitor, then breaking up with her because she can't trust her anymore. She's also sick with a respiratory illness that causes her to cough up blood and will, without a cure, presumably kill her. But Sarah's daughter's bone marrow keeps her healthy enough, and little Kira is eager to help her Aunt Cosima stay alive.

5. Helena

Though she might on occasion leave you locked in a cell as revenge or threaten you with a knife, Helena is fiercely loyal to her "seestras" and just wants someone to love. She's also incredibly fascinated by kids, which is helpful, considering she's pregnant. Helena is Sarah's twin sister, but their birth mother gave them up: one to the church and one to the state. Unfortunately, the church didn't do such a great job at keeping Helena's sanity intact, so every once and a while there's a bit of a mess to clean up after she kills someone. But it's usually for a good cause nowadays.

6. Rachel Duncan

Rachel is a power-hungry mess who is pretty easy to hate at first. She's manipulative in her treatment of those most loyal to her, ruthless when she knows what she wants but is thwarted in every attempt to get it and just evil enough to seem like the most inhuman of all the clones. She seems every bit worth hating until some of her past is revealed: She loses her father, and suddenly as the tear falls down her cheek, it feels as though nothing in the world should ever dare to hurt this poor clone ever again. But don't worry, it will. A pencil in the eye probably hurt more than losing her father did.

7. Felix Dawkins

Felix is Sarah's foster brother and her greatest ally, even before the whole Clone Club mess came about. Not only is he Sarah's closest—and possibly only—friend, but he also becomes quite close with the other clones as well. He shows up to Alison's play even in the midst of complete chaos in clone world, and in fact he shows up for Alison just about any time she needs him, which is pretty faithful considering their first encounter involved her almost shooting him. His apartment/art studio serves as home base much of the time for Clone Club meetings, a hideout and a general place to hole up when everywhere else is too unsafe. Ironic considering he keeps his door locked with a screwdriver stuck through it.

8. Paul Dierden

Honestly, it's a little hard to keep track of what team Paul is playing for half the time. Sometimes he's left in the dark; sometimes he's pulling all the strings behind the scenes. Originally he was Beth's boyfriend and monitor, but then he fell in love with Sarah while she was pretending to be Beth. He's worked for Rachel and slept with her, and he's worked with Castor, the male clones project. Paul's been all over the place, and occasionally his intentions were doubtful, but in the end, he was a hero.

9. Donnie Hendrix

Aka, Donnie Chubs. Do not underestimate Donnie in the beginning because he gets so, so good. His best roles include: father, husband, friend, monitor, drug dealer and accidental murderer. At first he seems like a bit of a pushover—especially when his wife ties him up and tortures him with art supplies—but eventually he's just a caring, thoughtful, ambitious guy who loves his wife and will almost get his fingers cut off in order to help her out.

10. Delphine Cormier

You know, she's never been with a woman before. Delphine is many things: Cosima's best friend at school, fellow wine-stealer, crazy science geek and gunshot victim. She falls in love with Cosima, and they hole up together in their neat little lab to make crazy science together. Eventually things stop working out, both for their relationship and for Delphine's life in general. She's probably dead. It's a shame.

11. Siobhan Sadler

Siobhan is Sarah and Felix's foster mother, and she has connections. Everywhere. With everyone. But it seems her connections only get everyone deeper into trouble than they were in when they began. Once she kidnapped Sarah's daughter and hid her in the woods. Then she killed her old friends there. She's a pretty shady lady at times, but she's also crazy supportive and only wants the best for her foster kids. Even though Sarah is technically a clone of Siobhan's own mother. It's all a very complicated relationship.

Don't even get me started on the fact that half of these characters are all played by the same actress. She's so talented, you'll probably forget that fact half of the time you're watching.
