The Battersea Bats are a gang of four kids who have their den in an abandoned building near the Thames, and they have a plan of action in mind because in about a week there is a soapbox derby being held, a contest they mean to win.

A man who works for 'The Party' (an all powerful empire led by a man known only as 'Big Brother') begins to have thoughts of rebellion and love for a fellow member. Together they look to help bring down the party.

Sunday Night Theatre was a long-running series of televised live television plays screened by BBC Television from early 1950 until 1959. The productions for the first five years or so of the run were re-staged live the following Thursday, partly because of technical limitations in this era, and the theatrical basis of early television drama. Some of the earliest collaborations between Rudolph Cartier and Nigel Neale were produced for this series, including Arrow to the Heart and Nineteen Eighty-Four. The Sunday night drama slot was subsequently renamed The Sunday-Night Play which ran for four seasons between 1960 and 1963. ITV transmitted its own unrelated run of Sunday Night Theatre between 1971 and 1974.
