Last Breath 🎥 2025 Movie Info

Plot Summary

Chris Lemons, Duncan Allcock, and David Yuasa are members of a team of saturation divers who work to maintain undersea gas lines in the North Sea. While on rotation, the divers live onboard a vessel in pressurized chambers which maintain conditions required for diving and working at 300 feet below sea level. The divers are transported to and from these chambers by a pressurized diving bell, which is lowered to depth from the ship and allows the divers to remain at pressure for the entirety of their four-week work rotation.

During a deployment, Lemons and Yuasa exit the bell to begin work on an undersea gas line manifold, while Allcock remains stationed in the bell to monitor their status and attend to the umbilical lines that supply them with communications, hot water and breathing gas. Lemons and Yuasa navigate to the manifold and prepare to begin their work, but on the surface in heavy seas, their vessel’s Dynamic Positioning System experiences a malfunction, causing the ship to begin drifting away from the work site. The bell is dragged along with Allcock still inside, and Lemons and Yuasa scramble to climb to the top of the manifold so that they will be unobstructed when they are also pulled along.

Yuasa successfully ascends the manifold, but Lemons’ umbilical line becomes entangled in the structure. Yuasa, realizing that Lemons’ umbilical will snap within moments, tells Lemons to switch to his backup air supply, which will provide him with ten minutes of emergency oxygen. He promises to come back for Lemons, but tells him he must be on top of the manifold for Yuasa to be able to locate him. Moments later, the umbilical snaps, leaving Lemons behind with only his emergency air supply and no means of communicating. Yuasa is carried away on the diving platform still attached to the bell and the ship. Meanwhile, on the ship’s bridge, the crew look for solutions to the DPS’s malfunction.
