All hell breaks loose at a local high school when a very effete men’s tumbling and rhythmic gymnastics club is suddenly joined by a gang of the school’s “baddest” boys and proceeds to make believers out of everybody around them. Casting a spotlight on the Japanese-born sport of men’s rhythmic gymnastics, "Tumbling" is an uplifting and inspirational passion-of-youth drama about true friendship, dreams and the wonders of hard work. But will they all be tumbling like pros by the end of their dramatic run? (Source: TBS)
