Not every fairytale gets a happy ending. Cassan O'Brian, normal teenage boy, is going through a lot in his life right now - dealing with his crazy friends, enjoying the summer in his smaller-than-a-pebble town, and oh yeah - getting over his twin brother's dissappearance. Aiden, Cassan's twin brother, has been missing for three months now, with no traces and absolutely no hope of return. But when one clue, in the form of a homeless girl getting over a drug addiction, presents itself to Cassan, his boring summer turns into the adventure of his life. With his friends and the girl, they visit Underlend, where Aiden is supposedly kept. But not everybody turns out to be who they're portrayed as, and in this modern version of the classic Alice in Wonderland, more than lives are at stake.
