37 Seconds is a French drama miniseries inspired by true events. It follows the relentless fight of a mother after her son, a fisherman, disappears at sea when his trawler sinks under unexplained circumstances off the coast of Brittany. The vessel goes down in just 37 seconds, leaving the crew no chance to survive.

Refusing to accept the official explanation of an accident, the mother embarks on a long and exhausting legal and personal battle to uncover the truth. Confronted with institutional silence, political pressure, and military interests, she takes on a powerful and opaque system, determined to obtain answers at any cost.
