"After hearing his classmate Roland Culver brag about his own grandfather, Verne decides that he wants to meet his grandparents. Verne, Jules and Marty head back to Wyoming on March 3, 1850, a date that has been carved on a wagon buckboard as the day that Daniel Clayton and Martha O'Brien married while on the Oregon Trail. As it turns out, Martha is a tough frontier woman, while Daniel is a mild-mannered scholar who collects butterflies. When Martha sees Marty, she falls in love with him, and Jules and Verne have to reunite their mother's parents. To complicate matters, Martha is kidnapped by an outlaw, \"Wild Bill\" Tannen."@en .

Verne, Jules and Marty head back to Wyoming on March 3, 1850, a date that has been carved on a wagon buckboard as the day that Daniel Clayton and Martha O'Brien married while on the Oregon Trail.

When Martha sees Marty, she falls in love with him, and Jules and Verne have to reunite their mother's parents. To complicate matters, Martha is kidnapped by an outlaw, \"Wild Bill\" Tannen. In 1991, Clara is slowly fading away, and complaining about how the carving on the buckboard has been erased. She remembers the wording, however, and Doc takes the locomotive to travel back to 1850. Verne rescues Martha from Wild Bill, but the two face a new threat from a bear. With Daniel along for the search, Doc realizes that the area as the future site of the Yellowstone National Park, and recognizes the Old Faithful geyser. Under Doc's instruction, Verne and Martha throw a buffalo hide over the geyser, and mere moments later, a column of water elevates them up and out of danger. Doc and Daniel fly in with a homemade glider. When Daniel comes to Martha's rescue and their eyes meet, they fall in love and the wagonmaster conducts their wedding that evening. History is back on track. Verne finds out that his meek grandfather had discovered a new species of butterfly, and at the next show and tell in 1991, presents a book showing an illustration of Lepidoptera martha. Everyone is impressed, even Roland Culver."@en . .
