Military service recruit Miguel Canete (José Luis Ozores) Roncalejo neighbor, provides a serious family conflict. Miguel has a brother, Pipo (Miguelito Gil), aged six, who lives with him and is not willing to leave his side. Back in Madrid, at the destination of Four Winds, Miguel becomes his good faith and simplicity, the target of an endless series of hazing, always related to the sergeant Palomares (Manolo Moran), instructor of recruits. The tribulations of the recruits are complicated when it appears, in full command, Pipo, who was impossible to stay in the base has to seek other accommodations as.
