On a summer evening in northern Sweden, when the sun doesn't quite set, Dunderklumpen (an animated character) comes out of the woods to seek some friends to keep him company. He comes upon a "human" house of the Wolgers family where Dunderklumpen finds toys belonging to a boy named Jens and his young sister. Using his magic, Dunderklumpen brings the toys to life and takes them away to the woods where he lives. This adorable and amusing crew includes the small but fiercely brave lion Lionel, the demanding toy girl Doll, the cute harmonica-playing bear Pellegnillot, and the ridiculous Dummy the Bunny.

Jens hears and sees the toys crying for help and follows Dunderklumpen who is not so quick to surrender his new-found company. They are also followed by Jens's Father who goes searching for his runaway son and is accompanied by the dutiful Bumblebee. Dunderklumpen also has a small locked chest (that he took from the children's room) with him and believes it contains a great treasure. One-Eye, an old nemesis of Dunderklumpen, also seeks the treasure for himself and pursues our heroes. No one knows what the contents are but Dunderklumpen and One-Eye are both sure it's priceless. One-Eye's signature tool is a small counterfeiting machine he uses to beguile the toys and Dunderklumpen.

Following Dunderklumpen into the woods, Jens meets a flower with the name Blossom, which travels on an umbrella and helps him along the way. The gang also meets the flying paper Malte (one of Jens's drawings come to life), the living-talking mountain Jorm, and an elderly woman named Elvira Fattigan who's an old friend of One-Eye.

In the end Elvira reminds One-Eye that his fall from grace came after encountering human materialism, and soon the chest is found to contain a feather, a dandelion and a rock that are considered treasures to a child. Realizing the chest had no valuables but cherished treasures, everyone celebrates in song and dance, One-Eye becomes friends with Dunderklumpen, the toys stay behind with the both of them and Jens and his father return home together.
