Prabhu Selvaraj (Tamil version)/Adi Tomar (Hindi version) (R. Madhavan) is a failed boxer who, despite being very talented, falls victim to the dirty politics in the boxing association. Ten years later, he is a coach for the women's boxing teams but is extremely angry and frustrated with the partiality in selection. Due to his rift with the association head Dev Khatri (Zakir Hussain (actor)), he is falsely charged with sexual harassment and transferred to Chennai. Despite the very poor infrastructure, Prabhu/Adi manages to find talent in a roadside fish seller Madhi (Ritika Singh), who he notices while she is thrashing the judges during her sister's tournament.
