Sangram Bhalerao a.k.a Simmba (Ranveer Singh) is a dirty cop, who never misses a chance to win a bribe. His view towards his responsibilities changes, when his sister Aakruti Dave (Vaidehi Parashurami) is brutally raped and murdered by drug peddlers. He then pledges to punish the culprit, local goon Durva (Sonu Sood), and his gang members, while also swearing to work ethically here on.
