Stand Up plunges into Mayan myth, delving into rituals at the Copan ruins on the Guatemala-Honduras border. Guided by Modesto Sanchez, a renowned Maya scholar, Gip and Miki explore topics like pelota, sacrifices, and the substances the Maya regularly consumed. In the subsequent chapters of this episode, they navigate Costa Rican forests hanging from steel cables while practicing canopy tours.

Shortly after, they find themselves at Playa Zicatela for a stop on the Longboard World Championship, aiming to grasp the differences between short and long surfboards. Following a night of beer-drinking in a friend's local establishment, Miki wakes up with memories etched all over his body.
