Dead dogs lie (2001)

Three hit people - two men, one woman, who have never met before are placed on a road trip down the East Coast together. The only thing they have in common is that they have all worked for the same boss - and, as they swap stories, discover that they have all screwed up for this same boss in the past. As they share their stories of errors on the job - seen through visual, stirring flashbacks - they begin to wonder why it was they were put together in the first place and what might be waiting for them at the end of their little road trip.
