In the Summer of 2024, Paris is hosting the World Triathlon Championships on the Seine for the first time. Sophia, a brilliant scientist, learns from Mika, a young environmental activist, that a large shark is swimming deep in the river. To avoid a bloodbath at the heart of the city, they have no choice but to join forces with Adil, the Seine river police commander.
