I saw the movie Golden Job.
This is the story of a band of 5 men who are friends and like brothers and who are mercenaries. After one deal goes bad, they decide to be more moral in their work, but one brother brings them to a job in which they rob a truck carrying gold.
The brothers become alienated and separated. The four brothers then go back to get the gold from the bad guy.
The original capture of the truck with the gold is interesting!
