The end is built into the beginning.

A theater director struggles with his work, and the women in his life, as he attempts to create a life-size replica of New York inside a warehouse as part of his new play.
Synecdoche, New York keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9 of the E0–E14 reality ladder, compressing identity, memory, mortality, purpose, consciousness.
Films fighting at the same level of reality, about the same things.
The same preoccupations examined at another scale — one mind versus a nation.
