Plot Summary:

In a decaying pizzeria, a group of Withered animatronics—Foxy, Bonnie, Chica, and Freddy—struggle against the Fazbear Protocol, a digital network that binds their consciousness to the facility. Haunted by their origins at a diner in London and the past actions of the Toy Animatronics and Puppet Foxy. Foxy seeks a way to liberate his partner, Mangle, who is deeply integrated into the building's network. After Foxy confronts and kills Don Afton in the office, the group resolves to initiate a final stand to destroy the pizzeria and the Toy animatronics.

Bonnie engages in a brutal confrontation with the Toy Bonnie, while Foxy and the others fight to break the Puppet Foxy and Toys control over the facility. Following the destruction of the building, the group successfully makes it outside. However, the severance from the network proves fatal for Mangle, who passes away as she experiences real rain for the first time. Grief-stricken but determined, the surviving animatronics decide to travel to Scotland to seek a new existence, and to bring back Mangle. They are unaware that they are being tracked by the Shadow Syndicate.

Trivia:

The episode is officially the first episode of the season and series. But the Pilot Episode is still canon to the series, despite Scroll of the Dragon instead using FNAF McFarlane Toys instead of FNAF Funko Pops.

The series introduces three new characters, Balloon Springtrap, Don Afton and Puppet Foxy.

This is the first FNAF Series to be set fully in the United Kingdom and Northern Ireland. 

The episode takes place in London, and then Edinburgh.
