Vincent has an extraordinary ability: his strength and reflexes increase tenfold when in contact with water. To make full use of this gift, he settles in a region with many lakes and rivers, which is isolated enough to allow him to live a peaceful life. Then, one day, during an aquatic escapade, he encounters Lucie.
