The tale begins in Mumbai where a gang of robbers is sweeping through the city. Officer Jai Dixit (Abhishek Bachchan) is brought in on the case and he is on the trail of the robbers - a gang led by Kabir (John Abraham). Jai ropes in the services of Ali (Uday Chopra), a carefree garage mechanic and a prodigious biker. With fast bikes, big action, DHOOM reinvents the classic cops and robbers tale.
