Tammi is annoyed. Instead of traveling to Formentera and presenting her followers with dreamy photos, her mother Simone takes her to the middle of nowhere to attend the funeral of her grandfather Jackel, a complete stranger. There she also met her aunt Britta and her children. There isn't even cell phone reception in the boring amusement park, and Tammi has little or nothing to do with her cousin Umbo and Cousin Cookie. But suddenly something incredible happens: During a thunderstorm, three worn-out ghost train characters come to life - the witch, the giant and Rumpelstiltskin. Tammi recognizes them as perfect allies to wreak havoc and finally escape this boring wasteland. But unfortunately she did the math without her own family and the stubbornness of the spirits. Suddenly everyone has claimed the amusement park for themselves and a wild chaos ensues.
