Traffic Signal is a story of one such signal, which is representative of all other signals around the city. Silsila a young orphan, who was born and who took his first tiny step at the signal is now its manager. For him the Signal is his workplace and a home where he lived. He's a sensitive soul with a heart of gold who considers the people like his family. He loves all those working at the signal, which in a way is his family but would spare nobody when it comes to business. He has a mentor, named Jaffar, who also is the collector of his region. Both he and Jaffar work for the local Mafioso, Haji and would even lay down their lives for him. Inherent in the social structure, lies a nexus between the local Mafia and Politicians, though at that level Silsila is almost nonexistent. Yet by a force of circumstance Silsila gets drawn into the bigger game and finds himself to be responsible for the annihilation of his own world, something to which he's dedicated his life. His deeds are irreversible and he would most certainly not be able to get things back to normal. What would Silsila do in such a situation? Someone who had never hurt anybody in his lifetime. A person with a heart of gold who was left to fend for himself and the future of those who'd been devastated because of him. Silsila being a practical person knows that he can never take on Haji who is too powerful and way beyond him. Yet no matter what and how he has to get his life and the lives of his family at the Traffic Signal back on track how he gets around to do it is the summing up of the film Traffic Signal.
