Millions of years ago, dinosaurs roamed Drumheller and the badlands of southern Alberta. The town is the home of thousands of dinosaur fossils and bones. When the city of Drumheller goes to sleep each night, the dinosaurs awake and reassemble themselves. A dinosaur roars out for the others to join him and they begin they very own celebration. Dinosaurs dance, play the drums and make a lot of noise. The adults dismiss the noise as a storm, but the children know better! They go to dance and frolic with the dinosaurs, until the sun starts to rise and they have to go back home to bed.
