WELCOME TO THE JUNGLE is the story of a film unit in jeopardy. Sinha (Zakir Hussain) is a rich businessman who gets a tip from a government insider, Ramprasad Udayvar (Brijendra Kala), that if the opposition party wins the upcoming elections, he’ll be jailed for financial fraud. Ramprasad advises him... to indulge in loss-making to prevent himself from landing in prison. His trusted aide, Dubey (Johny Lever), advises him to make a grand flop film. The idea is to cast flop actors and directors so that there’s no chance of the film becoming a hit. Accordingly, Dev (Rajpal Yadav) and Das (Paresh Rawal) are hired as directors and Nainsukh (Shreyas Talpade) as the cinematographer. Rajiv Kohli (Akshay Kumar), an unsuccessful actor, is cast as the lead. Dev and Das are unable to repay the loan of dreaded gangsters Romeo (Arshad Warsi) and Yeda Anna (Suniel Shetty). When the gangsters learn that the director duo is working on a film, they order the latter to hire them. Sinha’s daughter Jenny (Jacqueline Fernandez) and Rajiv’s ex-flame Nadia (Disha Patani) are signed as actresses. More actors also join in, such as Rambo (Krushna Abhishek), Jumbo (Kiku Sharda), Rangwa (Mukesh Tiwari), Jagwa (Yashpal Sharma) and Daler (Daler Mehndi). They proceed to a hilly area to shoot the film. For the final schedule, the unit lands up in a town named Azadganj, which is terrorized by a dreaded mujahideen, Zatara (Jackie Shroff). Since the characters in the film are playing army officers, the villagers and the terrorists assume them to be Indian Army officials. What happens next forms the rest of the film.
