Three friends – Meet (Vivek Oberoi), Prem (Aftab Shivdasani) and Amar (Ritesh Deshmukh) – are married and dont like their wives. Meet thinks his wife Unatti (Karishma Tanna) is having an affair with her boss, Prem doesnt like it when his wife Tulsi (Manjari Fadnis) doesnt spend quality time with him and Amar hates his marital life because his wife Mamta (Sonalee Kulkarni) is more concerned about their son, Pappu. One day, the men receive an invite from their college, SLUTS (Sri Lalchand University of Technology and Science), to attend their college reunion. Their wives dont come with them, so the three decide to have Grand Masti there to escape their boredom. When they arrive, they see the women fully clothed and the men too afraid to express their love for them. This all due to the fear of Principal Robert (Pradeep Rawat), who hangs people naked on a tree if they disagree with his rules. They find out that their former student, Hardik (Suresh Menon), is in a mental asylum because of the principal. Meanwhile, Prem meets one of his former teachers, Rose (Maryam Zakaria), and is attracted to her. Meet meets Marlow (Kainaat Arora) and is attracted to her. Amar meets Mary (Bruna Abdullah) and is attracted to her. The men then goes to the womens place to have sex with them. But just when they were about to do it, they find out that Rose, Mary and Marlow are relatives of the principal. The principal chases them down thinking they had sex, but they get away as their wives come to spend time with them. The trio then get an MMS showing them the footage of them having sex. Luckily, the video doesnt meet the eyes of their wives. They find out that it was Hardik who sent them the video, and he blackmails them. Their task is to kill the principal to fulfill Hardik's revenge. They fail in killing him, so they decide to try to delete the videos off Hardik's phone. They succeed and continue to spend time at the reunion.
