A cunning burglar is wreaking havoc in Stockholm. As the panic spreads, Daadh is under great pressure to apprehend this masked thief, who is known to be both dangerous and violent. He is close to getting caught, but escapes, whereupon Daadh is offered help from the renowned hypnotist Cagliostori, who happens to be performing in the city. Daadh allows himself to be hypnotised, falls asleep and wakes up in a most unpleasant situation where his very life is in danger.
