A teenage swimming sensation sees his career careen off the rocks due to ego and booze and eventually becomes a bitter, but effective swimming coach. An overeager mother brings her son to him, who has failed to place higher than fourth in any competition. The young swimmer soon begins to improve while his mental condition deteriorates as a result of the coach’s violent and abusive tactics. Eungyo director Jung Ji-woo puts together a compelling character study that highlights dangerous ambition in a country where parents have been known to push their children to extremes to overtake their peers.
