It's been 15 years since the race between Walter the Tortoise and Murray the Hare but the competition is still strong. When they hear about the upcoming Mt. Impossible Nature Adventure Race, they can't resist the opportunity to challenge each other to a rematch! This time they get their children to be their teammates. When Walter and Murray get separated from their kids, the two dads must team up to find them and learn there are far more important matters than winning a race. The movie stars the voices of Jay Leno, Keke Palmer, and Drake Bell.
