Along with Jeff, the staff writer, and Arnau, a fellow intern, the three go on a road trip to a coastal town. While Jeff just wants to chase after his high school crush and Arnau wants some kind of life experience, Darius spends her time with Kenneth, a man who believes that he has built a time machine.
