A British drama student, in New York without a green card, Claire takes the only job she can get: working for a firm of divorce lawyers, posing as an easy pick-up in hotel bars to entrap straying husbands.
When one of her targets becomes the subject of a murder investigation, the police ask Claire to use her acting skills to help lure their suspect into a confession. But right from the start, she has doubts about the part she's being asked to play. Is Patrick Fogler really a killer . . . Or the only decent husband she's ever met? And is there more to this set-up than she's being told?
And that's when Claire realises she's playing the deadliest role of her life . . .
