Bassie and Adriaan, a clown and an acrobat, oversleep and lose the circus where they work. They will have to look for a new job. They try out different jobs, from baker to waiter. In fact, this should work, were it not for the constant harassment of a certain Plague Spirit. This bully, who is always dressed in a black cloak and a jester-based mask, makes everything go wrong. Fortunately for the two, they still have their friend Douwe, who, like the Plague Spirit, shows up everywhere and helps the two as best he can.
