Tangkis revolves around Fuad, a former national badminton champion who harbors a massive dream of breeding world-class athletes by strictly training his own children. The film explores themes of high-stakes ambitions, familial sacrifice, and the toxic or difficult balance between rigid sports discipline and a father's genuine love. While Fuad primarily focuses his efforts on coaching his two sons to make the national team, his daughter, Sara, steps up to challenge his authority as both a coach and a father, igniting deep-rooted emotional conflicts within the household.
