Two violators of the military service law are incorporated as soldiers recently arrived from Europe and proposed to integrate a group that will operate in a jungle region, for which they have to prepare for difficult survival missions.

Following the events (and disasters) at the end of their previous adventure, Alberto and Jorge are severely reprimanded. However, just when the recruits' fate seemed destined for the brig, a direct call from the Lieutenant General saves them from punishment... though to do so, they must prove themselves in a new training environment for their first special mission.

Alberto and Jorge are fulfilling their obligations as conscripted soldiers who have violated the law of mandatory military service. They have committed so many blunders that everyone from the corporal to the lieutenant colonel in charge of services is confessing to the chaplain, telling him that because of this pair of useless men, the entire company has been punished. The higher-ups order the commanding officer to assemble the men he deems capable of withstanding the high risks of a second mission to be carried out deep in the jungle. The commanding officer doesn't hesitate for a moment to include Jorge and Alberto in this high-risk group, without realizing that they themselves are the real risk. The final film in the conscript saga.
