The film opens with Alfie Wickers (Jack Whitehall) having taken Class K on a school trip to Amsterdam. Unbeknownst to him, Mitchell (Charlie Wernham) has spiked his crepe with magic mushrooms, causing Alfie to hallucinate while in the Anne Frank Museum. He believes Jing (Kae Alexander) is a panda and is convinced that the Anne Frank dummy is alive, which leads to him stealing it from the museum (in a parody of E.T. the Extra-Terrestrial) and ends up in a canal.
