That makes him detest Jean Pierre, the lifeguard from the neighbouring tower, who is slow, disorganised and delighted to carry out rescues in the water. A neutral, close-up gaze that in just a few highly revealing scenes shows us the difficult relationships between Mauricio and both his fellow lifeguards and the bathers.
