Ajay Devgn and R Madhavan starrer Shaitaan dropped its trailer today. Directed by Vikas Bahl, the film looks like a fun watch. 

The trailer teases R Madhavan’s character, who has hypnotised Ajay Devgn’s daughter. R Madhavan’s Shaitaan enters Ajay Devgn’s home, where he stays with his daughter, played by Jyotika. Madhavan enters their house with a promise of leaving after 15 minutes but, when asked to leave, doesn’t budge. 

When Ajay Devgn's character forces him out of the house, his daughter goes against him and tells him that he will stay back. It is then revealed that R Madhavan's character has hypnotized the child- to such an extent that she ends up slapping herself and even hitting her father.

The story starts from there.
