They describe the story of the movie on the official website as follows:
Mages (Masters) and Heroic Spirits (Servants) work together in the battles of the Holy Grail War… a fight for an omnipotent wish-granting container called the Holy Grail.
However, this war has become horribly twisted.
A young woman named Sakura Matou, with the sins she has committed, drowns in the murky darkness.
A young man named Shirou Emiya, who vowed to protect Sakura, works together with Rin Tohsaka and throws himself into the raging battle to put a stop to the Holy Grail War.
Illyasviel von Einzbern, as one of the few who knows the truth behind the conflict, confronts her own fate, while Zouken Matou uses Sakura to try to fulfill his own desires.
“That’s why… you’ll need to grit your teeth, Sakura.”
Will the young man’s wish reach her even as he challenges fate itself, battling against the rising tide?
The Holy Grail War is coming to an end…
The final battle is about to begin.
As mentioned, Heaven’s Feel is the final story arc of the main visual novel. The first story arc, which featured Saber as the heroine, was animated into a television series by Studio DEEN in 2006. The second story arc titled Unlimited Blade Works and featured Rin Tohsaka as the heroine received a movie adaptation in 2010 from Studio DEEN but was eventually remade by ufotable into a two cour television series in 2014.
