Tamera Mowry-Housley as Gethsemane

BRAN'S MOVIE SYNOPSIS

Gethsemane is riding her bike by a castle one day and sees smoke coming out of it. So she goes to check on it and she totally interrupts the shot of this ghost hunting show. When they realize who she is, the producer Ciara asks if they could interview her. They heard that she solves a murder with the help of the paranormal and would love to chat with her. She's not so sure.

The next day at school, Griff asks her to get together later. She's like i'm in. Just then, inspector O'rielly comes and asks if she could help him brush up on his piano skills before his family comes into town. She agrees.

Bad news guy, the showruner KentDempsy is found dead by the crew as they're wrapping the shoot. Naturally, Gethsemane can immediately see and talk to him. He's like pretty I'm a ghost, huh? He's like there's all sorts of tension between the crew. Not to mention Ciara is his ex-wife.

Ghost Dempsy and Eamon listen in as the police discuss how his injuries line up with the injuries of a fall. But there's no where in the room he was found in where he could've fallen. So he must've been moved.

One of the crew, Rahj, is especially suspcious. I guess he owes money and is on the run from this mystery guy.

Claire brings Gethsemane some evidence she has of a thermal camera showing someone they assume is Kent being pulled from behind. So they go to that room and they find a hidden door. Behidn the hidden door is a stair case. They go down and see a little bit of blood, and some blue stuff on this screw driver they find. Ciara recognizes it as belonging to Liza. To make matters worse for Liza, there's audio that sounds like her all but admitting to the murder. Gethsemane suspects its AI.

Roj is found dead. There's this dude that Gathemne suspects may have wanted him dead because he was too much of a sceptic. they ask him on a lvie stream and he tells them to scram.

Turns out, it was that dude's son that did it. So take that!

She helps the inspector with the piano preformance and they hold hands afterwards. So maybe more on that later.
