“Three Jolly Fellows” tells of the adventures of three small men in a world that borders on the fantastic: the composed and close-to-nature Mossbeard, the irritable city dweller Halfshoe, and the sensitive poet Muff. An old woman’s inexplicable love of cats has lured many felines to the city. Risking their lives, the diligent and ready-to-help fellows lure the gang of cats out of the city, with the result being trouble in both the city and nature.

The second part of the film based on Eno Raua's children's book of the same name, which tells about the activities of three jolly fellows - Sammalhabe, Kingpool and Muhvi. The movie viewer can join their exciting adventures in saving the city from the rats.
