DEAD CALM (1988)

Plot

When their sailing holiday is interrupted by the sole survivor of a sinking schooner the high seas turn to terror for a husband and wife. His story of sickness and death is really of madness and murder and they must now throw their all into a battle to survive. A superb and unbearably tense thriller, with Nicole Kidman, Sam Neill and Billy Zane as the unhinged gooseberry.
