One night on a lonely highway| a speeding car tosses a satchel of money| meant for somebody else| into Jane and Alan Palmer's back seat. Alan wants to turn it over to the police| but Jane| with luxury within her reach| persuades him to hang onto it "for a while." Soon| the Palmers are traced by one Danny Fuller| a sleazy character who claims the money is his. To hang onto it| Jane will need all the qualities of an ultimate femme fatale...and does she ever have them!
