Two lonely strangers, an out-of-town hotel. . .what could be the harm in a little extracurricular activity? But before Jean and Frank can say Was it good for you, honey? a camera flashes, and they are trapped in a dirty cop's blackmail sting. And Fallon, the cop, throws in the hapless cameraman for good measure. A bored suburban housewife, a computer consultant slumping into middle age, and a petty thief frantic to stay out on parole?it's no wonder Fallon and his cronies see the trio as the perfect patsies. But the blackmailers soon discover that underestimation is a dangerous game, as the patsies turn the tables, transforming themselves into that fearsome sword of retribution, The One-Night-Stand Gang.
