Stephanie - bored housewife and down-trodden mother - wants a job, and Madeleine's recruitment company seems the obvious place to go. Except that PAs isn't quite what it appears. Far from providing companies with Personal Assistants, the agency offers Perfect Alibis to unfaithful women. And as Stephanie soon discovers, there are lots of them about! Founder member Patsy, is a serial philanderer and there's even a dark side to best friend, the blissfully-married Millie. For the well-heeled ladies of Edenhurst, PA's is a ticket to risk-free adultery. When slacker Troy, Stephanie's first love, returns unexpectedly, even she is tempted. But her life is soon in turmoil, and that's before the tabloids get involved.
