Qayamat Ki Raat

Raj and others then manage to rescue Karuna and take her to the old and desolate temple that used to be the Tantrik's lair 25 years ago. On seeing Karuna distraught and weak due to a near death experience, Gauri insists on taking her inside the temple. Her decision is strongly challenged by Raj as he is sceptical of the temple, but Gauri breaks the holy threads wound over the gate and enters the temple's premises. Seeing this through the gem of the ring on his hand, Kalasur directs his hand to reach for the temple door and find Birju who is revealed to have been possessed by the Tantrik and locked in a room in the temple's basement since 25 years. Meanwhile, Gauri searches for help in the temple, while Raj and Aman have left to find a way out of the woods. Gauri accidentally trips herself and falls down the stairs to the basement, exactly like the way Suhasini had. She is startled to notice the possessed Birju who later attacks her with an axe. She struggles to save herself but is cornered by Birju. Just when he is about to kill Gauri, a man arrives and grabs his hand firmly. The two then fight while Gauri yells for help.
