Comedy-drama series about the best robbers in town. After fifteen years of living it up on the Costa del Sol, Maurice Riley and Syd Woolsey are back in Blighty. Mo is determined to keep his promise to his wife and not return to crime, but Syd's son is in trouble and the only way they can help bail him out is to rob again. With the help of their old colleague's son, Hedley, the boys try one last job. Or so they say.

Maurice and Syd are shocked when Knacker, a copper from their past, rents the flat below them. Maurice struggles to keep him away from his visiting daughter, who doesn't know about his criminal history. Things get much worse for the boys when Knacker reveals he has evidence that could send them both down for a very long time - unless they do a job for him.

Maurice becomes obsessed when the one safe he failed to crack comes back into his life. Despite Syd and Hedley's warnings that the safe is cursed, Maurice is adamant he can finally beat it. Grace becomes suspicious of her father's behaviour.
