James vs. His Future Self

A scientist meets a version of himself from the future who has traveled back in time to stop himself from inventing time travel. When an uptight time-travel-obsessed young scientist is visited by his nihilistic future self, he's told that he needs to give up his dream of becoming the world's first time traveler--or else. But when he won't go along with the plan, it becomes a wicked battle of man versus himself--literally.
