-At the start we learn that everyone who's been touched by the Necronomicon has visions of others that have touched the 3 Books as well as a vision a 'Harbinger of Evil' that will arrive very soon.
-Evil Dead (2013) and Evil Dead Rise are revealed to have happened at around the same time.
-Brandy having seen Mia in a her vision picks her up right after she's escaped the Burning Cabin.
-Pablo and Kelly meet up with Beth who has been put in jail while the cops investigate the apartment.
-By the time Pablo and Kelly break her out the Evil has taken the Cops and the rest of the building.
-Elsewhere at the Lake Cabin from Rise the other friends finally arrive and start getting taken by Evil starting a larger spread unbeknownst to the heroes.
-After their experiences Mia and Beth have visions of the 'Harbinger of Evil' as well.
-The Heroes must bring together all three Books to stop this Harbinger.
-Pablo and Kelly already have Book 1.
-Brandy and Mia retrieve Book 2 from the Burnt down Cabin and then they fly to California to meet Pablo and Kelly but must contend with Evil Dead on a plane, very nearly crashing as a result.
-Meanwhile Pablo, Kelly, and Beth have to fight their way back up into the Apartment to get Book 3.
-They all eventually come together at the location from their visions which turns out to be the lake from Rise.
-They find the place infested with Deadites.
-Before the last battle the Ghost Beaters reveal the weapons they've prepped in case Ash ever came back.
-They give Beth the Boomstick and Mia the Chainsaw. Pablo even helps her attach it to her missing hand.
-They attempt to perform a ritual with the 3 books but must also fight back the Deadites causing the ritual to ultimately fail.
-The Harbinger's portal then opens up and Ash steps out.
-The movie then shifts for the last 30 minutes or so to Ash's journey from the future.
-He's lead to believe by the Knights of Samaria that the Necronomicon can send him back to the past to hopefully stop the apocalypse they now live in.
-They also present him with The Kandarian Sword.
-He must journey to the prophecied location and speak some words that will send him back.
-There's only one road that leads to the portal and it's Deadite Country.
-Mad Max Evil Dead ensues with the most suped up Delta there's ever been.
-When Ash reaches the location he reads the words (that He's written down this time) and a portal opens.
-It is then revealed to Ash as he goes through that the Knights of Samaria have been infiltrated by the Dark Ones, their plan being to turn the Chosen One into the 'Harbinger of Evil' thus kicking off the 'Reign of the Deadites'.
-We then see the same scene of him stepping out of the Portal in the present and seeing the rest of the group.
-They're all thrilled & relieved to see him but now knowing what he knows Ash can only greet them with an uneasy smile.
-The expressions of relief slowly drop from everyone's faces.
-Kelly: "Oh fuck... What'd you do now?"
-End of Part 1
