The trailer of Amazon Prime Video's original show Bestseller was released on February 8. The trailer reveals the central conflict of the show as a stalker/troller of a celebrated author targeting everyone around him. The author here is Tahir Wazir, and when he is attacked, he is also struggling with writers' block. 

Fortunately, he meets a fan of his, played by Shruti Haasan, who inspires him to write his next novel. However, chaos ensues real soon as people close to the author, including his girlfriend, played by Guahar Khan, get attacked.

The identity of the person behind these attacks and the role that Tajir's books, especially his most recent novel plays, will be explored in the show. The person who investigates this case is played by Mithun Chakraborty.

Bestseller is directed by Mukul Abhyankar and produced by Siddharth Malhotra’s Alchemy Production LLP. The psychological thriller also stars Satyajeet Dubey and Sonalee Kulkarni. The show is set to premiere on Amazon Prime Video on February 18.
