It's London, 1920. Newly demobilized soldiers have flooded the capital's streets but an ungrateful country isn't ready for them. You think crime doesn't pay?
Harry Costello has returned from the horrors of the Somme to no job, no money and no prospects. Desperate times demand desperate measures and when an opportunity to burgle a house presents itself, Harry seizes the chance.
When Harry and his brother Frank are blackmailed into paying off a local hood they decide to take care of the problem themselves. But when all of London's underworld is in thrall to the man's boss, was their plan audacious or the most foolish thing that they could possibly have done?
You think crime doesn't pay? Meet the Costelllos - the kind of criminal family that might make you change your mind.
