Orphan Black is an action thriller television series that debuted in 2013 on BBC America. The fourth season is set to begin in April 2016.

Orphan Black begins by introducing viewers to Sarah Manning, a woman back in the states and on the run from an abusive relationship who is trying to get in contact with her young daughter whom she hasn’t seen in over 10 months. She’s getting ready to take the train when she sees a woman commit suicide right in front of her. Interesting twist: this woman looks exactly like Sarah. She decides to assume the dead woman’s identity and lets herself into the woman’s apartment.

Everything seems to be working out perfectly when she realizes the woman has $75,000 in the bank. She decides to drain the woman’s bank account and then skip town with her daughter and her foster brother. Her plans are cut short when unfinished business from both the dead woman’s past and her own past come barreling into her life, leading Sarah down a deadly trail of thrilling mystery that all lead her to the stunning conclusion: she is a clone, there are more of her out there, and that someone is trying to kill all of them. Sarah has no choice but to continue to live a double life as herself and the dead woman, as she meets other clones and realizes that they are all entangled in a complicated plot as genetically identical individuals who all grew up in very different circumstances.

Highlighted by a tour de force performance by Tatiana Maslany (she plays all of the clones, giving each of them distinct personalities, speech patterns and behaviors), this is compulsive television viewing.
