Pickpock is behind bars. But more elusive than Arsène Lupin, no chain resists him and he plays with policemen like a cat with mice. After having masterfully taken them for a ride, having brought them down to an effigy, he rolls them up and throws them out the window. But the policemen come back to life and the chase goes on. Pickpock, caught a second time, locked up behind heavy bars, finds a new way of escaping and imprisoning in turn the policemen.
