The Peruvian army captain Pantaleon Pantoja, a very serious and efficient officer, is chosen by his superiors to set up a special service of 'visitors' to satisfy the sexual needs of the soldiers posted on remote jungle outposts. At first unhappy about this assignment, he nonetheless puts his remarkable organizational skills in action and in a short time has his 'unit' running smoothly. In the home front things get complicated though; his wife dislikes his long hours and the secrecy surrounding his work, and he, despite being a dedicated husband, feels tempted by one of his "subordinates".
