Ловушка (4)

Sapphire and Steel arrive at a deserted service station and meet Silver. A couple from 1948 arrive together with an old man from 1925 and a travelling player from 1957. The agents are suspicious as to the lack of interest shown by the couple in the modern trappings of the petrol station and the strange unused condition of the musician's tambourine. The strangers are revealed as Transient Beings, enemies of Sapphire and Steel, who have escaped entombment in the past using a device called a Time Box. They use a Time Box to trap Sapphire, Silver and Steel in the petrol station and the agents find themselves floating through the infinity of space: trapped forever.
