"A Copper's Tale" is a character driven period crime drama detailing one of the biggest investigations of the post-war period, conducted in the full glare of public and media scrutiny. It is told from the perspective of Tommy Butler and his elite team of brilliant, idiosyncratic investigators, all with different methods and opinions.

"A Robber's Tale" tells the story of how the robbery was inspired, planned, rehearsed and executed. Beginning with a previous robbery at Heathrow Airport in November 1962, the film tells how Bruce Reynolds assembled and led the gang that targeted the August Bank Holiday 1963 mail train from Glasgow.
