Sapphire & Steel (1979)

S1E5 Assignment I: Escape through a Crack in Time (5)

The time break intensifies when a nursery rhyme concealed in a book lodges itself in Helen's mind. In an attempt to remedy the situation, Sapphire sets the nursery rhyme book ablaze, while Steel and Lead struggle to contain the expanding time break. The kitchen ends up in disarray, prompting Helen and Rob to assist Sapphire in tidying up, with Steel and Lead monitoring the upstairs area. However, things spiral out of control when two additional pools of light emerge from the bedroom, causing Rob to mysteriously vanish.
