Sapphire & Steel — Season 6

Assignment VI: The Trap

At an abandoned service station and its adjoining café, time has stopped. Operator Silver has arrived first assessing the situation. Sapphire and Steel remain uncertain as to exactly what they are supposed to be investigating. The key may lie in two humans in the café who claim to be from 1948, a service station worker, and a travelling performer, but something envious and sinister gets closer before a trap is sprung.
