Swop tells the story of three friends: Sef, Wesley and Marjory. One day, they discover an abandoned washing machine that seems to possess mysterious powers; it lets you swap your own head with someone else's. This presents the three friends with a range of possibilities. For every problem they face, they can think up a solution by exchanging heads. It goes without saying that this is not the right approach to take because it often leads to confusing and comical situations. But once they've swapped heads, they are literally able to see the world through different eyes. As a result, they go through a transformation that enables them to ultimately resolve or accept their own problems.
