A young up and coming director with friends in high and dark places makes a proposal to a production committee to give him full auteur control over their next big project. To his immense surprise he actually gets it but on the condition that he puts together 2 cour anime multimedia franchise starter within a year.
Unfortunately, due to pressures, politics and massive executive meddling, the project spirals completely out of control and turns out to be a massive flop. His reputation in tatters, he decides the only thing to do is to vanish himself completely in the forest around Mt Fuji.
He comes very close to death there but before he was gone for good, a mysterious spirit appears before him and offers him a bargain. If he promises to come back to this same spot and day by the end of the bargain and offer up his life to it, the spirit will turn back time as many times as he needs to complete his perfect anime.
The director takes up the bargain and finds himself back to the proposal meeting that started it all. With as many do-overs as he needs, the director begins his descent through madness and hell to make the magnum opus of his industry.
I was probably thinking of Aoi Honoo and the Re-take doujin when I came up with this. Didn't come up with an ending for it then but I'd put forth that he bring a portable dvd player to the forest with him to watch with the spirit before retiring for good.
