Murdock (Bo Swenson) leads a daring bank robbery, though when the robbers try to get away things start to go wrong. Only Murdock manages to get away after he stuffs half a million dollars in cash in a post box. Now he has to find out a way to get the cash out of the post box before it is collected.
Unfortunately, a couple of people noticed what he did. One is a petty drug pusher (Michael C Gwynne) and the other a young woman Mary (Cybill Shepherd) who wants to get him into bed... and get her hands on the cash.
Although the premise is a little silly at times this is a solid film with a good relationship between Murdock and Mary. The action scenes which book end the film (the first being the robbery and chase) are both very well done.
