Cash-strapped single mom Louise Evans (Jodie Whittaker, Venus) gets a high-profile promotion at her London bank, but at an unexpected cost. The tough, ambitious young woman quickly learns that the price of her position is entry into a criminal underworld she never dreamed existed.

Soon Louise becomes entangled with a ring of ruthless killers prepared to do anything to pull off their multimillion-pound scam. But she could use a little money herself, and she doesn't quite trust the amorous undercover cop (Toby Stephens, Jane Eyre, Die Another Day) who insists he wants to help her.

In a world where nobody is quite what they seem, Louise keeps everyone guessing where her loyalties lie. Also starring Laurence Fox (Inspector Lewis), Riz Ahmed (Four Lions), and Charlie Brooks (Bleak House).
