The “equilibrium” at the beginning of the film represents what is for the main character(s).

normal

Explanation:

At the beginning of the narrative, the starting point is referred to as equilibrium. This is the state during which we meet the characters and their lives, see what is usual for them and how things go during the state of balance. That means the equilibrium shows the normal state of things in the life of the main character.

The conflicts, changes, and rising actions start only around the second stage, after the period of equilibrium has been disrupted and the normal state is turned into the unusual.
