Following disaster and the loss of their ship due to a German submarine, reporter Porter (Tallulah Bankhead) ends up on a lifeboat surrounded by debris. She doesn’t remain alone for long; others join her, and when German passenger Willi (Walter Slezak) appears, there are nine people in total. Their goal is to reach Bermuda, but the route is unknown except perhaps to their captive—though they resist trusting him or relinquishing control of the journey. As provisions dwindle, conditions worsen, and rescue seems increasingly unlikely, they face difficult choices. What follows is a story about these survivors as they confront their situation and examine how they’ve lived and misrepresented themselves. This small group becomes a pressure cooker of conflicting emotions—partly poisonous, partly romantic, largely filled with suspicion. Even adrift at sea, some characters are intent on trying to outdo each other, even if it's just in deceiving those around them. It's clear that the film was shot in a tank on an LA backlot, so the visuals don’t always hold up today, but ultimately, the narrative is what makes this such an engaging experience. Alfred Hitchcock gradually reveals information, sometimes believable and at other times contradictory, and the sound design effectively creates a strong feeling of confinement despite being surrounded by ocean with people you wouldn't necessarily feel comfortable trusting. Tallulah Bankhead delivers a wonderful performance, as does Henry Hull, contributing to a distinct wartime story that, if intended as propaganda, provides an interesting glimpse into how divided even those on the same side could be.
