I watched this movie yesterday . Any of one who has given positive review can help me by answering the below question. In the second scene itself , shine tom kills his partner rajisha. and remaining scenes are his struggle with dead body and managing 2 friends and rajisha's father arrives. after this Rajisha -live comes to the flat and had a fight with him. Here also shine chacko hit her with electric iron. Next scene Rajisha is going in car with shine's dead body and tells police that she killed her husband Now what a common viewer should understand . which is fantasy and which is reality
