Pat and Mat have moved into new houses, and every odd job turns into a new adventure. A mole in the garden, a blocked chimney, a fence, a swarm of bees, a solar lawnmower or a security camera: nothing stops the two handymen, though their solutions rarely go as planned.

When two enthusiastic handymen become neighbors, they can't let clumsiness stop them from finishing all their new home projects.

The clumsy Pat and Mat are back in their movie Buurman & Buurman, experimenteren er op los! The two men face all kinds of challenges. For example, Pat and Mat try to bake pancakes in a hilarious way, they try to catch the apple thief by securing the apple trees and they even experiment with a homemade flying machine! And well, why would you go to a car wash when you can build one yourself? It only makes the car a bit dirtier ... All in all, experimenting is not easy for the neighbors, which means that this time and again things are going wrong ...
