David (Mauricio di Yorio) is not like your ordinary teenager. He obsessively works on his body—day and night—to reach the idealized self of a bodybuilder. His mother Juana (Umbra Colombo), a well-known artist, controls David’s every move and behavior, overseeing all aspects of her son’s regimen and his daily weightlifting training. As David dedicates himself to further developing his physique, his social life begins to call out to him. His clique of male friends, who relish making lewd and inappropriate jokes whenever they hang out, begins to beckon David to be more outgoing—while attractive classmate Mica sets her eyes on David and works to win him over.
