Plot Synopsis

Ten-year-old Dan Henderson can answer almost any question about dinosaurs, and when he can't, he conducts a dino-experiment with any of the 18 CGI-animated dinosaurs that only he -- and viewers -- can see. Set in a modern day suburb, a typical day for Dan involves racing dinosaurs on a Go Kart track, finding dinosaur bones in the schoolyard or saving plant eating dinosaurs from the clutches of meat-eaters like the mighty T-Rex. And while his classmates are always up for a good dinosaur fact, story or explanation, the teachers and adults in Dan's life -- played by an all-star cast of celebrity comedians including Andrea Martin, Mark McKinney, Kevin McDonald, Sean Cullen, Jayne Eastwood and Jon Dore -- need a bit more convincing. Nick Jr. aired the U.S. premiere of this series on Sunday, October 17, 2010 at 7pm ET/PT.
