Manhattan lawyer Louden Trott is about to marry his tycoon boss Simon Worthington's spoiled-rotten daughter Wendy, albeit with a crushing prenuptial. Simon however makes him interrupt the preparations to make sure in person that nobody Nikki Finn, just released from a New York jail, takes the bus to meet her Philadelphia parole officer. Picking up a cat (actually a rare mountain lion) for even richer Montgomery Bell proves bad enough, but Nikki takes the cake when it comes to provoking, manipulating and surprising. Furthermore they are tailed by a couple of criminal goons and a bickering pair of police detectives who are after the key to evidence which Nikki claims proves she was framed by corrupt Worthington.
