In "Minotaur" a family gathers on Christmas Eve. Like all families, this family holds itself together with lies, illusions, cliches. Over the course of a night and day, those lies, illusions, cliches begin to break down under the pressure of repressed truth. This is the basic meaning of the play's title: at the center of every labyrinth, there is a monster (a monster which takes many shapes, including our own).
The play is about truth: truth as the overhearing of ourselves, through the encounter with other people; encountering other people, and ourselves, in other people. Letting all the pieces collide against each other, and then being able to--finally--see a sort of pattern in the fast chaotic images.
