Wazir 'est un conte de deux amis improbables, un grand maître d'échecs en fauteuil roulant et un brave officier ATS. Réunis par la douleur et un étrange coup du sort, les deux hommes décident de s'entraider gagner les plus grands jeux de leur vie. Mais il y a un adversaire dangereux mystérieux, tapi dans l'ombre, qui est prêt à les faire échec et mat.
Shaitan starts off with Amy (Kalki Koechlin), who is mentally disturbed and deeply affected by the attempted suicide and eventual institutionalisation of her mother. She moves from Los Angeles to Mumbai, where she meets KC (Gulshan Devaiya) at a party her parents forcefully take her to. KC introduces her to his gang – Dash (Shiv Pandit), Zubin (Neil Bhoopalam) and Tanya (Kirti Kulhari). They lead a directionless life, having fun, drinking, using drugs and driving around in a Hummer. On one such occasion, they start racing a random car and win. In the celebration rush, they run over two people riding on a scooter, killing them instantly.
