Triangle (2009)

Christopher Smith crafts an unrelenting nautical nightmare that literalises the Sisyphean agony of maternal guilt upon a deserted 1930s ocean liner. As Jess encounters mounds of identical corpses and discarded necklaces on the deck, she realises her instinctive struggle to rescue her autistic son is the very engine driving the eternal slaughter. It is a devastating portrait of self-inflicted punishment, where maternal grief refuses to let go even when the cycle promises infinite horror.
