A recruitment office in the tropical heat of La Republic de los Mosquitos. Beneath the turning fans, wearing only white pants, the boys wait to undergo close inspection. Initiations, maneuvers in battle dress, abuse from NCOs, pillow fights, the squabbles and sexual tension of young men deprived of female company.

A care-free young man wanders the countryside, crossing his path with experiences he ultimately shares with the younger son of a doctor. Alone and free, he wanders the countryside. In farms and villages both good and bad luck come his way; a farm boy, a young toff, a cute stable lad, a forward young fisherman. All cross his path. But nobody keeps him for long and he always leaves alone. Always? No, the younger son of a country doctor, fleeing from his incestuous brother, follows him on his travels. They share everything; friendship, adventures, the lessons of life - and meetings with other boys.

From the three incarcerated guys fucking each other behind bars, to the safe haven of the infirmery where the doctor pays attention to those members most in need - Service Actif 2 takes up where Service Actif 1 ended. Classic Cadinot fare!
