Amy works for Doug selling drugs as a way of getting money to be a good mother to her little sister (Ella) and partner to her girlfriend (Sue).
Amy is on parole and in possession of a few small sell bags when she is picked up Harrison a detective wanting her as a confidential informant. Agreeing to work for Harrison she is released and immediately contacts her friend Isaac, her connection to an Ukrainian drug importer (Yuri).
She is told that Doug wants to sees her. She goes to see Doug on the way to Isaac's to drop off the money. Doug sends her to drop a car off to Karl, Doug hired muscle. To avoid raising Doug's suspicion Amy is forced to leave Ella and the money at Doug's house. This sets off a race against the clock to get back and get the money to Isaac before Yuri's men turn up with the drugs.
Amy makes the mistake of offering a deal to Karl. While going to pick up a car with Karl offsider (Jonas) Karl informs Doug. Karl contacts Jonas, Amy's paranoia makes her panic and shoots Jonas.
Amy can't go back to her money and forced to try and raise more money from her buyers. This backfires resulting in a failed ambush of Yuri's gang. Beth, Doug's girlfriend attempts to beat information out of Amy's little sister, which Doug takes offence too.
As the noose closes on Amy she realises that everyone she loves is better off without her. She sets out to get revenge for her sister (not knowing her sister is okay), an sacrifices herself to break Ella free from the life Amy had misguidedly setup.
