Saint Nicholas is wrongly accused of keeping people awake at night, he and his Black Pete have to prove their innocence.

Saint Nick and Black Pete's nightly roof roaming is disturbed by loud party noises from bells, balloons and even drums, Pete thinks a 'bat birthday party'. That reoccurs every night, keeping people awake and grumpy, so they turn on the Saint who is seen there and presumed guilty of the ruckus. In fact shopkeeper Frutselia profits by selling bizarre tranquilizing products, and pushes her son Milan to help keeping the town awake so he can earn enough to court teacher Eline, who also fancies him. Saint and his friends must prove his innocence to regain popularity.—KGF Vissers
