In the bustling London of the 1960s, a group of peculiar inmates from a maximum-security prison embarks on a daring plan that would challenge even the cleverest criminals. The charismatic and cunning leader of the group, jewel thief Ted, has devised an ingenious scheme to make off with a substantial haul during a carefully orchestrated escape. Along with his best friend, a less experienced thief but full of good intentions, and a group of unusual accomplices, Ted faces not only the distrust of his fellow inmates but also the watchful eyes of the prison staff.
As the operation unfolds, things do not go exactly as Ted had planned. Amidst mix-ups, misunderstandings, and a couple of unexpected twists, the prisoners find themselves in a race against time. The situation becomes even more complicated when a group of detectives starts to suspect their plan, adding a comic tension to this scene of madness where everything can go wrong.
With sharp British humor and a perfect blend of absurd situations and endearing characters, this film presents a satire on criminal life and friendship through a showcase of mishaps. Each escape attempt not only tests their ingenuity but also the loyalty among them, leading the audience to a surprising conclusion that hilariously captures the essence of friendship and cunning in the world of crime.
