This was advertised as Mumtaz's last film (even the credit titles say so). And she did disappear after this film before reappearing almost 2 decades later in Aandhiyaan. The ichchhaadhaarii naag and naagin (serpents who can assume any form at will) are blessed with the ability to capture the image of their partner's killer in their eyes and do not rest till they eliminate them. So Reena Roy captures the image of these poor hunks in her mind, and eliminates them one by one.
Her second last target is Raj. She assumes the form of a girl who could end up being Raj's wife. Although Raj is paranoid by now, having lost so many friends, the naagin still manages to trick him into believing that she is Rajkumari. She plants a poisonous kiss on Raj's lips. As his vision clouds, he tells her,
"tumhaaraa chehraa dhundhlaa dhundhlaa saa..."
"tumhaarii aankho.n ke chiraaG zaraa dheeme paD gaye hai.n"
He has not yet realised, that he has been poisoned. He asks,
"muhabbat aur maut me.n yahii hotaa hai"
"मुहब्बत और मौत में यही होता है"
Death and love cloud the vision. Fantastic line.
