Jose Luis is an executive at his parents' underwear factory where his girlfriend Sylvia works on the shop floor. When Sylvia falls pregnant, Jose Luis promises her that he will marry her, most likely against his parents' wishes. Jose Luis' mother is determined to break up her son's engagement to a girl from a lower-class family, and hires Raul, a potential underwear model and would-be bullfighter, to seduce Sylvia.—Murray Chapman
