7-year old CECILIA finds her mother EVELYN dead in the living room while her father BARRY cradles her in her arms. A knife lies by her side. Twenty years later, her girlfriend AUDREY breaks up with her because she spends too much time at work. Weeks pass and Audrey hasn’t reappeared. Worried, Audrey looks for her at a research center for a corporation called BLAZING WORLD. She’s not allowed inside, but one of the scientists, ISABELLA realizes this. She tells her that Audrey is hurt and needs help. She lets her into Blazing World where she discovers that Audrey has fallen under a coma, with her mind stuck inside a simulation of a horror movie. She says Audrey must enter the simulation and save her. They form the plan to end the movie by killing the villain, as they believe that will wake Cecilia up.
Audrey enters and she’s attacked by the RAPTOR KILLER. Cecilia rescues her. But inside the simulation, Cecilia doesn’t remember Audrey and seems fully convinced that the movie is her reality. The Raptor Killer murders Audrey. She wakes up from the simulation, briefly unable to remember who she is. They decide to make a trailer and show it to Cecilia. But this leaves her unconvinced and frightened about Audrey, believing she might be connected to the Raptor. She ties her to a chair but she seems to remember certain things from her real life like how to make tea. The Raptor appears again. They attempt to unmask him but doing so only makes them black out.
Audrey wakes up again, this time with Isabella begging her to recover her memory since NEIL, her boss is approaching. Neil discovers what’s happening and says that if Isabella doesn’t recover Audrey’s memory, she’s fired. Audrey recovers her memory. She tells Isabella they should escape with Cecilia and the equipment. She accepts and they flee, with Neil knowing they can still find it.
Once in Audrey’s apartment, she goes back into Cecilia’s movie. In the movie, they form a plan to destroy the Raptor by any means possible. They set traps around the apartment and finally they kill him. Once they unmask him, they discover that it’s Barry, Cecilia’s father. She can’t believe it and neither can Audrey. She also can’t believe that it didn’t work as the film hasn’t ended. Barry wakes up and kills Audrey. Cecilia goes into shock from the realization and wakes up in the real world. Now it’s Audrey who has fallen under the coma. Neil has tracked them down.
Cecilia decides to go back to rescue Audrey. Once there, she reunites with her but Neil has also entered the simulation. He kicks out Audrey and tries to convince Cecilia to stay in it because they can use the simulation to make a lot of money doing horror films that exist as a virtual reality experience and as an extension of the minds of the audience. But also, she can see her family alive in it. Once inside, she sees her mother again but realizes that she hasn’t aged as she would if she was still alive and that her mind tried to convince her of things that weren’t true about her family. She can live in reality and enjoy life as it is. This angers Neil who merges into her mother and tries to kill her. But Cecilia overpowers him and escapes. He’s stuck inside the simulation. A year passes and the movie premieres to great acclaim. Barry and Cecilia make amends, as do Audrey and Cecilia. They decide to rekindle their relationship, having fun both inside the Blazing World and in the real world.
