Ping (Ingfah Waraha), a fierce, beautiful and rebellious spirit medium, escapes from the Jarn-Pued-Fah Foundation after being unable to endure the horrors within. She tries to convince her best friend Bam (Praewa Nichapat) to run away with her, but a fight causes them to part ways. On her own, Ping meets four chaotic guys heading to the wild “PARADISE SEVEN” pool party: Pee, the party-loving playboy Ter, the sarcastic tech nerd Jok, the funny influencer full of bizarre stories Dung, the mama’s boy doctor. The night is full of music, booze, and seduction, with Bam stealing all the attention. But the next morning… Bam is found dead — and no one remembers anything. Who did it? Is the killer among them? The mysterious Lieutenant Dan (Jam Rachata) and intense Captain Chat (Jeng Big Ass) take on the twisted case.

The morning after the party, everyone wakes up to find Bam missing. The shock deepens when her body is found in Dung’s car trunk! Could one of them be the killer without knowing it? None of them remembers what happened. Now, Pee, Ter, Jok, Dung, and Ping are all suspicious of each other. Pee becomes even more wary after seeing Ping fight violently with Bam before the incident. As tension grows, Ping discovers a new ability: she can see Bam’s ghost! But it doesn’t help much — even ghost Bam is still drunk and remembers nothing! With both the living and the dead clueless, they must team up to uncover what really happened at the party — and who the killer is.

The case heats up when Ping suspects that Dung might be the killer. Furious, she starts distrusting the whole group — Pee, Ter, and Jok — while growing desperate for answers about what really happened to Bam. Meanwhile, ghost Bam begs them to move her body out of the car before it starts rotting. The gang scrambles to relocate the corpse to a cold place as fast as possible. Just when things couldn’t get worse, Lieutenant Dan and Captain Chat show up at the hotel to investigate Ping — while the killer is still at large!

Pee secretly hides Ping’s money, fearing she might run away. Amid the chaos, Ter and Jok chase a new lead to a tattoo studio. At the same time, ghost Bam senses someone is about to open the freezer where her body is hidden! If it's discovered, the whole gang could end up behind bars. Ping must stall for time with a bold move. Meanwhile, at the tattoo parlor, the story takes a wild turn when Ter becomes the next suspect — completely out of the blue.
