A hostage thriller/ethereal deep sea exploration romance, primal connections to the water, the womb and each other.

Deep stuff. Very Wim Wenders. The vibe of this trailer for the film based on the J.M. Ledgard novel has only the vaguest hints of plot elements of other movies, but a strong vibe of “The Abyss,” “The Big Blue” and other immersive, spiritual pictures plunging into the sea.

Looks and feels romantic, tragic and deep. May 18,
