Theo is a tiny clementine with a huge problem: his father makes him wear a swimsuit made of lead that weighs 100 kilos, for 100 days. He sinks like a stone, the whole club laughs at him, and even a chair breaks under him. But why would a father do this to his son? Behind the suit hides a secret: Bruno was once a legend called The Anchor, until a rigged final destroyed his career and his family. Now the house is about to be seized, a traitor sells Theo's weakness, and the terrifying champion Drake is waiting for him on day 100. Every day he gets stronger. Nobody knows what happens when the suit comes off.
