A routine arson case sends New York PI Barney Moon to what he regards as an Alien Planet -- Los Angeles. His should-be one-day mission quickly escalates to murders and conspiracies, trapping him in LA - and in growing danger. Worse, Barney doesn't drive, a problem he solves by apprehending gorgeous would-be car-thief, Melodie, 18. Narrowly evading assorted bad guys, LAPD detectives and at the last second, violent death, this comically mismatched pair foils a bizarre terror plot just as it's about to kill thousands.
