Akash Rana (Ajay Devgan) is upset. So upset that he plans to blow up a train packed with passengers heading from London to Glasgow. He’s upset because four years ago he was deported from the UK and now he wants to avenge himself and teach the UK authorities a lesson about messing with illegal immigrants. For some reason screenwriter Robin Bhatt wants us to be sympathetic to the plight of the illegal immigrant which completely defies logic, reason and, well, the law.

Akash’s accomplices are illegal immigrants Megha (Sameera Reddy) and Adil (Zayed Khan). Their target is a train; their goal is to get the authorities to cough up at million Euro before they diffuse the bomb on the speeding train. On the first day of his retirement cop, statesman and actor (that is how he is described in the film) Arjun Kapoor (Anil Kapoor) is called back on duty to lead the investigation into the bomb threat and to catch the perpetrators.

At the control room in London, railway traffic controller Sanjay Raina (Boman Irani) is trying to maintain his composure and manage a complex grid of rail tracks and trains. He is determined to keep the passengers safe, not just because it is his duty but also because his daughter is on this particular train.

Director Priyadarshan intersperses the suspense-less crime with extended police-criminal chases (raft, bike, car, jet ski and parkour). Unfortunately the police force appears to be completely amateur, just like the acting by the supporting cast, and makes the simplest arrest look challenging. The main ensemble cast of actors is also less than impressive, with perhaps only Anil Kapoor displaying some control in spite of the shoddy material.

With bits and pieces picked up from a host of Hollywood thrillers, Tezz is unoriginal in content. Its clumsy construction is what we have come to expect from these proposal films backed by producers who would rather insert an item number than develop any connection between the audience and the protagonists. Tezz was derailed even before it released.
