Seoul, 1986. A raucous gaggle of Korean teenagers spill out of the Gimpo airport and onto buses that transport them to a location just outside the city. There, these high schoolers sent from all over the world-the U.S., Mexico, London, and Hamburg-are participating in a government-sponsored summer program to help them connect with their heritage. With a summer of partying ahead of them, they're on a crash course to bring shame to their families, their ancestors, and their hosts-but with any luck, they might just figure out how to make friends, fall in love, and absorb some of their roots along the way.
