Two boys are kidnapped by three escaping convicts and the relationship which develops between captor and captured brings out the good side of the most dangerous criminal's character.

Terry and June Medford are both middle aged and beginning to find the trials of life are more difficult as they try to succeed in their daily lives. The couple have just moved to Purley, south-east London... Aunt Lucy and the mynah bird had disappeared, as had the occasionally visiting daughters. Terry and June now mixed with a friendly next door neighbour, Beattie; Terry's chatty work colleague, Malcolm; and their gruff boss Sir Dennis Hodge. Otherwise, things were much as before, with Terry's pigheaded childishness causing no end of problems, usually thwarting June's attempts at leading a cosy life.
