The trailer of Nawazuddin Siddiqui's upcoming project 'Costao' has been unveiled.

Set against the backdrop of 1990s Goa, Costao tells the story of a customs officer who dared to defy an empire built on smuggling, corruption, and fear. Nawazuddin is seen as "Costao Fernandes -- a sharp, unconventional enforcer whose bold tactics and unrelenting pursuit for justice puts him at odds with both the criminal underworld and the very system he serves."
