The series is a fictionalized origin story of the famous pen name "Mastram"—a legendary figure known for writing erotic Hindi pulp fiction in the 1990s and early 2000s. Unlike many adult series that focus purely on explicit visuals, Mastram focuses on the life of a small-town man named Rajaram, who adopts the pseudonym to write risqué stories, exploring the hypocrisy, curiosity, and sexual repression prevalent in conservative North Indian society.

The series features prominent actresses in episodic roles, including Tara Alisha Berry, Jagame Thandhiram fame Aanchal Sharma, Kajal Jaiswal, and Kenisha Awasthi.
