Gumnaam – The Mystery

Gumnaam – The Mystery starts with an unknown lady (Mahima Chaudhry) driving on a rainy night, who is eventually murdered as she drives, and her finger is cut off.

The story then pivots to one of an aspiring actress, Ria (also Mahima Chaudhry in a double role), who models and acts in music videos. She has her eyes set on making it big in films as a lead actress. During one of her shoots, she meets Dev (Dino Morea), a stuntman who saves her life during an accident on the set. She's impressed with him; soon love blossoms between them, and they are on a romantic high. Meanwhile, Ria is offered a lead role in a film by casting director Rishi Gandhi (Madan) on the condition that she leaves for Shimla the next day. Dev is very happy about her getting the role and sees her off, wishing her all the luck.

On reaching the film director's mansion in Shimla, she is introduced to the film's director, Muni Gandhi (Govind Namdeo), who praises her beauty and appreciates his assistant's perfect choice of casting her as the heroine. Slowly, Ria begins to see some unusual things around her. The director asks her to give a screen test; however, when she asks for a second take, she is refused. His assistant Rishi Gandhi delivers the cassette to Remon (Suman Ranganathan), a rich woman in a huge mansion in Shimla; the reason why he did so is not explained. Thereafter, Ria is not allowed to leave the mansion and is also not allowed to make phone calls. She notices that she is being spied upon by the casting director Rishi in her bedroom through a mask. Ria later explores the cellars of the mansion and, to her horror, finds the dead body of the unknown lady resembling her in a coffin. Her suspicions of the entire setup start building up.

The next day, when she wakes up, she sees that her hair has been cut and her finger has been removed, exactly like the dead woman in the cellar. Upon confronting the Gandhis, she realises that she is to be used as a pawn of extortion from Remon.

The rest of this thrilling drama unfolds, with Remon's role in the thriller being explained. Dev also becomes involved when he arrives in Shimla to look for Ria. The involvement of a rich uncle and his eventual murder by Remon further complicates the plot. Eventually, Remon and the Gandhis are brought to justice.
