Albert is Jonas's favorite stuffed animal, and they’re inseparable. But when young dog Luna decides she wants to play with Albert, her enthusiasm gets the better of her, and she accidentally tears him apart. While Jonas believes Albert can still be fixed, his uncle disagrees and throws the bear in the trash. Albert ends up in the compost bin where— surprisingly—he enjoys learning about the small animals and their daily tasks.

Despite this, Albert is determined to return to the heartbroken Jonas. Escaping the bin proves challenging, but with the help of new friends—Maud the maggot, Sofia the snail, Kelvin the beetle, and Timo the mouse—he might just find his way back. Will their efforts be enough to reunite Albert with Jonas?
