Highwaymen (2004)

"When murder is no accident, revenge is no crime."

James Cray watched as his wife was killed by Fargo, a hit-and-run serial murderer. After severely injuring Fargo and going to prison for several years, James is now determined to avenge his wife's death. He drives across the country looking for Fargo's 1972 Cadillac Eldorado, which the now-disabled killer has turned into a rolling death trap. James' search is helped by a state traffic officer and a singer with her own agenda.
