After a career-ending injury, tap dancer Sano Shuhei (Moriyama Mirai) finds himself in snowy Hokkaido, looking to marry his girlfriend, figure skating instructor Shizuka (Kato Rosa). Unfortunately his plans are put on thaw by Shizuka's disapproving father who has no intentions of marrying off his daughter to anyone anytime soon. Father dearest eventually agrees to let the couple tie the knot if Shuhei can coach the local junior hockey team Smilers to victory at the regional championships. Despite knowing nothing about the sport, Shuhei gamely takes on the challenge, which is more than can be said of his players. Without a smiler in the bunch, the Smilers have never even won a single match. Using atypical methods, Shuhei manages to get his scrappy team of discouraged misfits into some semblance of talent and teamwork, but will it be enough to beat the corporate-sponsored reigning champion, not to mention his stubborn father-in-law?
