The series focuses on a marine scientist called Abigail, who returns to her hometown of Fécamp to look into a shipwreck. However, the disaster causes tensions between various groups, including fishermen and environmental activists – though a greater danger lies below the ocean in the form of a mysterious entity.
The series stars Elle’s Fleur Geffrier alongside Andor’s Thierry Godard, King & Conqueror’s Jean-Marc Barr and Alpha’s Christophe Perez, and comes from creators Monica Rattazzi and Jonathan Rio.
Sea Shadows was called “an unusual and surprisingly effective mystery French series” by one viewer on IMDb, where it holds a 6.0/10 rating from fans.
