Tezz is the story of one man, who is out to get back what was unjustly taken away from him... the other is willing to do whatever it takes to stop him in order to serve justice; both are pitted against each other.. and both are pitted against time. Lives have already been destroyed and more lives are about to be devastated as a train speeding from Glasgow to London holds the fate of Aakash Rana (Ajay Devgan) and Counter Terrorism Command Arjun Khanna (Anil Kapoor), and only one of them will succeed.
