The Brazilian Antonio Das Mortes casts Mauricio De Valle as a mercenary peacekeeper. Agreeing to hunt down and kill rebel soldiers, the mercenary becomes increasingly drawn to the rebels cause. His 11th-hour turnaround does not prevent the film from ending in a bloodbath. Antonio das Mortes unabashedly casts its lot with such insurgents as Che Guevara. As such, this 1968 film had difficulty finding an American distributor until two years later.~ Hal Erickson, All Movie Guide
