What if people could actually go back to the past? The 15-year-old twins Roxy and Ray soon find out, when their eccentric Uncle Bob from Drumheller discovers two magical dinosaur eggs and builds a time machine. In the blink of an eye, the twins and their dog, Jasper, travel back to Alberta's early days. In Edmonton, while celebrating the province's birth in 1905 and its anniversary 10 years later, they meet many famous historical characters. As their amazing adventure continues, the trio boards a train to Calgary and, en route, comes face to face with a giant arm wrestler, train robbers, and a cage full of escaping rattlesnakes. A riskier leap back in time lands the twins and Jasper in 1912—at the very first Calgary Stampede! There, alongside colourful real-life rodeo stars, the twins set out to save the career and romance of their great-great-grandmother, a world class trick-roping cowgirl. With time running out, Wild Roping Roxy must somehow get the best of a deadly bucking bronco. And when Family Day Ray rides Hurricane, one of the meanest bulls in the land, the thrill of a lifetime could end in disaster...
