Sapphire & Steel (1979)

Episode Overview

Steel persistently mocks the soldier's ghost until he suddenly discovers Sapphire and Tully lying unconscious. They've found themselves in a corridor of the railway station, transformed to resemble a submarine where three young men perished due to asphyxiation. As Sapphire and Tully struggle to breathe, Steel heroically rescues them just in time, preventing them from sharing the same tragic fate as the submariners. Once safe, Sapphire and Steel decide to explore Tully's techniques further by conducting a séance to uncover more about the soldier's life.
