recounting the events of a freak diving accident and a rescue team's desperate attempts to rescue a fellow diver trapped on the ocean floor with only 5-6 minutes of emergency oxygen, last breath tows the line between being a lifelike documentary and a suspense film based entirely on true events. shown through a mixture of real footage, video interviews and recreations, it first aims to evoke the sense of isolation and vulnerability that comes with repairing deep underwater structures and living in a pod surrounded by darkness for extended periods out of necessity, as well as the kind of personality it takes to do such work. this soon transitions to capturing the sinking sense of dread of trying to save a colleague while everything is going wrong, still having so long to go before reaching your target, all while knowing you may already be too late. watch alone in the dark for maximum effect.
