Todorov's narrative theory ties in well with our film opening sequence. 

At the start there is a state of equilibrium (the way it should be) , the victim is at home watching TV and eating something. 

Further into the sequence there is a disruption, the phone rings and the victim starts to feel uneasy. 

The victim recognises the disruption and tries to repair the damage of the disruption by hanging up the phone and running away from the killer. 

Finally a new equilibrium is made, the victim is dead and everything is now calm.
