Highlights
In 1982, a young girl named Charlotte attends a birthday party at Freddy Fazbear's Pizza. She witnesses a man in a yellow rabbit costume, William, abducting a child. Despite her pleas to adults, Charlotte intervenes, rescues the child, but is mortally wounded by William. She collapses on stage, falls through a trapdoor, and is carried away by the Marionette, horrifying onlookers. Authorities blame Charlotte for her death, and the pizzeria is shut down, though a new branch opens later.
Twenty years later, an adult Vanessa is haunted by nightmares. Her friend Mike, unaware of her past, invites her to dinner. Mike's sister, Abby, talks about the first Freddy Fazbear's Pizza incident, believing the animatronics, possessed by child spirits, were her friends. Abby struggles with a harsh robotics professor, Berg, who dismisses her skills. Vanessa's father, William, was the murderer, leaving her marked by his actions.
Abby sneaks to the new Freddy's Pizzeria to find her animatronic friends. Mike, finding her note, rushes to the pizzeria. Abby is saddened the animatronics are still, but finds a 'FazTalker' toy. Meanwhile, content creators Rob, Lisa, and Alex are invited to the original, abandoned Freddy's by a guard named Michael. Lisa hears music, wanders off, and is attacked by the reanimated Marionette. Alex is killed by Foxy, and Rob is attacked by numerous animatronics. Michael, revealed to be Charlotte's ally, welcomes Charlotte back after Lisa's possession.
Vanessa is tormented by memories of her father. Abby hears Chica's voice through the FazTalker, asking for help, leading her to the original pizzeria. Abby and Chica are reunited, with Abby noting Chica's modified appearance. Vanessa learns of Abby's visit to the pizzeria, becomes terrified, and confronts Mike, who is upset Vanessa hid details about the child victims. Vanessa faces Charlotte at the pizzeria, revealing she set up a perimeter, but Charlotte states she has a new friend, Abby, to help her.
Abby's science project is destroyed by Professor Berg. She returns to the pizzeria, and Chica promises to be her project. Chica leads Abby to a control room, needing a secret code to unlock the perimeter. A tied-up Vanessa, watched by Charlotte via CCTV, is forced to provide the code. Charlotte wirelessly controls Chica to relay the numbers to Abby, who unlocks the perimeter, allowing the animatronics to leave. Abby and Chica take a taxi to the science fair.
Mike meets Henry, Charlotte's father, who explains William's true nature. Mike connects a drawing by Abby to the river at the original pizzeria, realizing Abby is in danger. Henry gives Mike a music box, asking him to leave it for Charlotte if he returns to the pizzeria. At the science fair, Abby and Chica win, but Professor Berg suspects a trick, insulting Abby. Later, Chica brutally attacks and kills Professor Berg. Mike finds Vanessa, who explains Charlotte (in Marionette) is controlling the animatronics wirelessly, seeking revenge on parents who didn't help.
Freddy, seeming like a costume, walks among people at FazFest. Mike tracks Freddy, but Chica activates prototype animatronics at the pizzeria. Foxy attacks Vanessa, causing a car crash. Vanessa saves an old couple from Freddy. Bonnie tries to attack a woman, but Mike disables the animatronics. Mike realizes one animatronic, Chica, is still active at his house. Chica glitches and reveals the Marionette inside her. Mike seeks help from the spirits of the kidnapped children. Vanessa confronts Charlotte, who possesses Abby. Mike uses the music box to free Abby, but awakened animatronics surround them.
Michael, Vanessa's brother, appears, revealing his intent to continue his father's (William's) legacy, using FazFest as cover for a massacre. When Vanessa refuses to join, Michael orders the animatronics to attack. The original animatronics, containing the children's spirits, appear and destroy the Toy versions. Michael attempts to flee but is stopped by Jeremiah. The original animatronics break down, returning to heaven after warning Mike about William's eventual return. Mike, feeling betrayed by Vanessa, distances himself. The film ends with Charlotte possessing Vanessa, hinting at further horror.
