Fast cars. Fast girls. Fast living.

In the 1950s, guitar-playing drifter Dude Delaney wanders into a quiet town looking to play music and generally cause trouble, much to the chagrin of the local sheriff, known as Sarge. While palling around with his B-movie-obsessed friend Nixer, Dude meets the beautiful Donna, and is offered a position in a rockabilly band, but the sheriff is intent on getting rid of him by any means necessary.
