Based on real events which saw two lighthouse keepers stranded for months at sea in a freak storm, the film tells a tale of death, madness and isolation; a desolate trip into the heart of human darkness.

In contrast to Robert Eggers’s horror outing, similarly drawn from the Smalls Lighthouse tragedy, Chris Crow’s chamber piece opts for a painterly naturalism that turns the all-consuming paranoia frighteningly intimate. Just like the tempestuous open sea, human nature also carries perilous depths.
