Dave, nineteen, has just graduated high school, with his three friends: the comical Cyril, the warm hearted but short-tempered Moocher, and the athletic, spiteful but good-hearted Mike. Now, Dave enjoys racing bikes and hopes to race the Italians one day, and even takes up the Italian culture, much to his friends' and parents' annoyance.
When Dr. Marcus Sommers realizes that he and his troubled, estranged brother David may be prone a fatal brain disease that runs in their family, he decides to make peace with his sibling, and invites him on a trip to the Rockies. There, the brothers bond over their shared enthusiasm for cycling and decide to enter a grueling bike race through the mountains. However, Marcus' health soon begins to fail, and David must compete without his brother at his side.
