Short track skater Lee Yeo-jun enters the national training camp for the first time, with only half a year left until the Winter Olympics. Overshadowed for years because of his weak stamina and timid personality, Yeo-jun never drew much attention. After the national selection trials, however, a series of accidents and injuries among top athletes suddenly gives him the chance to join the national team despite his lackluster eighth-place finish. The thrill of this opportunity does not last long, since the label “accidental national team” weighs heavily on his mind. At his assigned lodging, Yeo-jun meets Nam Ji-hoon, the strongest short track skater of the moment and his long-time secret crush. Ji-hoon seems unusually interested in him, and Yeo-jun quickly finds himself swept up in his orbit. On the day when sweat, relentless effort, and pushing himself beyond his limits are put to the ultimate test against destiny itself, there are exactly 166 days left until the Olympics.
