Sapphire & Steel

The time break strengthens after a nursery rhyme hidden in a book becomes stuck in Helen's head. Sapphire burns the nursery rhyme book and Steel and Lead barely succeed in stopping the time break from spreading. The kitchen is left a windblown mess and Helen and Rob help Sapphire with the clean-up effort while Lead and Steel keep watch upstairs. Everything takes a turn for the worse when two more pools of light escape from the bedroom and Rob suddenly goes missing.
