Margo (Maribel Verdú) is struggling to deal with her son Jon, a rebellious and free-spirited teenager who runs with a bad crowd. After Jon is expelled from school, Margo sends him to live with his grandfather Max, a retired military officer who lives in a small coastal town and believes he can fix his grandson with his own style of discipline. Max has hired Toni, a young man from the village, to act as Jon’s private tutor. Unfortunately, Jon is more interested in spending time with a local Colombian gang who are always getting in trouble and especially with Nelson, their cocky leader. Who is going to teach whom a lesson? This year’s Spanish submission for the Best Foreign Language Film Oscar.
