Jack Walsh is a Los Angeles based bounty hunter. It's a job he hates, he a former Chicago police officer who was, if rumors are true, run out of town by mob boss Jimmy Serrano. The reasons for his release from the force led to the dissolution of his marriage, his wife and daughter who he has not seen in nine years but who he still loves. Eddie Moscone, a bail bondsman for who Jack often works, convinces him to pick up a specific bail jumper, Jonathan Mardukas, whose whereabouts are unknown. Although Jack negotiates a lucrative contract with Eddie for this job - Eddie who will lose his business if Jonathan is not brought in within five days - Eddie believes Jonathan having been Serrano's accountant should be enough of a drawing card for Jack, Jonathan who embezzled $15 million from his mob boss. Using some contacts and a stolen ID, Jack is able to locate and capture Jonathan on the first day in New York. Out of circumstance, Jack and Jonathan are forced to travel by the proverbial planes, trains and automobiles to get back to LA as many others are also on their tail trying to get their hands on Jonathan. They include: Alonzo Mosely, an FBI agent, and his associates, who have been leading an operation against Serrano for several years; Serrano and his men who do not want to see Jonathan testify in court; and Marvin Dorfler, a rival bounty hunter who Eddie also hires just in case Jack fails, there being no love lost between Jack and Marvin. Some try to persuade Jack to give Jonathan up, using the "carrot" of more money than Eddie would be paying, while others have their own moles to be able to follow Jack and Jonathan's whereabouts as they snake west across the country. But the biggest obstacle in Jack getting Jonathan back to Los Angeles within five days may be mild mannered Jonathan himself. Beyond knowing he is an easy target for Serrano if he is in prison and thus who does whatever he can can either to persuade Jack not to turn him in or elude him, Jonathan, based on differences in personality with Jack including having a multitude of phobias, may drive Jack crazy and crazier the longer they are within each other's company.
