Filmmaker Mohit Suri's latest film Ek Villain is inspired by the South Korean revenge film I Saw the Devil. Although, it is quite evident that the action is toned down for the Indian audience.
It's a story of a serial killer who picks the wrong man's fiancee to murder.
Bad guy with a good heart Guru( Siddharth Malhotra) works for a local gangster( Remo Fernandez) in Goa. Life takes a pleasant turn once he meets the chirpy Aisha( Shraddha Kapoor) who wants to live her life to the fullest and has a joke for every occasion. Aisha's life is all about doing things for others and interestingly for one of her many cases she wants to take Guru's help. He doesn't seem interested but she for some reason is sure that he will agree and predictably so, he eventually does. A few scenes later, Guru and Aisha are married. The twist comes when a serial killer Rakesh( Riteish Deshmukh) on the loose kills Aisha. His is one of the many rude characters in Ek Villain. From doctors to the ticket collectors, everyone for some reason is arrogant and brash.
Now it's only certain that Guru will dig out Rakesh come what may, to the extent that even best security officers from the CBI are worried, not because there is a serial killer on the move but they fear Guru's revenge which can be ugly.
