After eleven years of coupled-up domesticity, Rory Carmichael is single for the first time in her adult life. When she discovers that Martin, her supposedly reliable Mr Right, is a distinctly unreliable cheater, she's forced to consider the possibility that everything she knows about relationships is wrong. In an effort to reinvigorate her love life, she sets herself a mission to date as many unsuitable men as possible. Maybe the bad boys she's never dated can show her what she's been missing in life.
