Following orders, rehearsing snappy marches and running through more drills than you can shake a drum stick at. A 19-year-old Argentinian man goes off into the army, where he becomes a drummer in a military band. A measured but poignant study of the collision between young individuality and military uniformity, which expands on the contradictions and uncertainties of entering into adulthood within the constraints of a rigid hierarchy. A coming-of-age story set in a "total institution".
