A Welsh family, the Owens, who bet on absolutely everything and anything, discover that their grandfather backed a winner on the day he died — but where is the betting slip? I'll Fly You for a Quid was Barker's favourite, and he initially chose to do as a series. However, the BBC convinced him that it would be harder to do a full series of scripts about Evan Owen in a Welsh gambling community compared to the prison setting of Prisoner and Escort. Barker adapted the idea into The Magnificent Evans (1984).
