Happyland centers on Lucy, the cynical teenage daughter of idealistic park princess mom, Elena. Having grown up in a world of manufactured happiness her whole life, Lucy wants to get out and experience something real. Then Ian, the new park owner’s son, arrives and sweeps her off her feet, leaving Lucy wondering if fairy tale endings exist after all. But when a scandalous secret turns her life upside down, she learns Happyland is far from a walk in the park.

The show premieres on Tuesday, September 30 @ 11PM ET/PT on MTV!
