Langa, a transfer student from Canada, meets Reki, a high school student who loves skateboarding. Reki seems to be hooked on “S,” a dangerous and secret race that is held in an abandoned mine. Langa, who was looking for a part-time job, heads to the “S” venue together with Reki as an assistant. There, the nemesis Shadow who caused Reki’s injury taunts Reki, and Langa, who has no experience skating, gets roped in, as well!
