Enrique, a 56-year-old Filipino bosun aboard an ageing bulk carrier crossing the ocean, has been declared medically unfit for duty. Trapped aboard, Enrique gradually fades from the crew's daily life as extreme heat, sleepless nights, technical malfunctions and metallic reverberations begin to reshape the world around him. Meanwhile, the crew continues the physically demanding work of cleaning the cargo holds and finds moments of joy, humour and connection to endure life aboard. As his isolation grows, Enrique becomes increasingly drawn to the disturbances affecting the ship and its crew, sensing that they may somehow be connected to him.
