Out on a fun-filled trip to Zoo Gardens, the Morris family’s amusement soon turns to amazement when bright lights flash across the sky. They suddenly find themselves in Horrorland-where admission is free, but the fun never starts. After a narrow escape from the house of mirrors and a chilling whitewater coffin cruise, Luke and Lizzy rejoin their parents at the front gate, but it’s locked! Now their only hope is to compete in a gruesome game show that proves what the world has feared all along: monsters really do exist…and they have their own cable channel.
