Happy-go-lucky Rick Jarmin (Mel Gibson) did a good turn fifteen years ago when he gave the government a much-needed testimony in a court case that put a dangerous drug dealer behind bars. The Witness Protection Program kept up its side of the bargain, moving him around over the years and hiding his identity. Now they have him working in a Detroit gas station, but his cover is blown when a former girlfriend, Marianne Graves (Goldie Hawn) discovers Rick at about the same time that the now-released, and very angry, drug dealer has caught up to him. A shootout ensues and Rick and his ex barely escape with their lives. Now the former lovers must flee together; on the run they rediscover their shared past as they desperately try to keep one step ahead of the killers.
