It's What's Inside (2024) Timeline Explained – Every Event in Order

Forbes orchestrated the game as revenge for the college incident where his friends chose Dennis over him after his sister Beatrice was found with alcohol. The incident led to Beatrice's mental breakdown and hospitalization, and Forbes blamed the group for not supporting him. He used the game to make them experience the same betrayal he felt, though his true motives were even darker, his sister Beatrice had already switched bodies with him before the party and was the one actually controlling the revenge plot.

Foreshadowing: Forbes arrives seemingly forgiving and wealthy, which seems inconsistent with someone who was expelled and had his sister institutionalized.

Each guest attaches an electrode to their head connected to Forbes' machine. When Forbes activates it, everyone's mind switches into another person's body. Forbes tracks who is in which body and can reverse the switches at the end of each round. The machine can also perform permanent switches if someone smashes the button forcefully enough.

Foreshadowing: Forbes mentions it's a 'top-secret invention' he developed in the tech sector.

Two peopleWho dies in It's die: Reuben and Brooke. During Round Two, Reuben (in Dennis' body) and Brooke (in Maya's body) confess their attraction, have sex on the rooftop, and the balcony collapses, causing them to fall to their deaths. Their bodies are lost, meaning the people inhabiting them (Dennis and Maya) have nowhere to return.

Foreshadowing: The group warns about the dangers of the roof earlier in the party.

Years before the movie, Forbes got into a fight with Dennis at college. Campus security arrived and discovered Forbes had given his underage sister Beatrice alcohol. The group sided with Dennis over Forbes, leading to Forbes' expulsion. Beatrice had a nervous breakdown from the scandal and was committed to a mental hospital. The fight was actually triggered by Dennis having an affair with Beatrice.

Foreshadowing: The friends are surprised and uncomfortable when Forbes arrives, and the timeline notes this incident had serious ramifications.

Beatrice blames the friend group for the cascading consequences of the college incident. She was underage, got caught with alcohol provided by her brother, suffered a public breakdown, and was institutionalized. She also resented that Dennis, who had an affair with her, framed Forbes for the fight and the group believed him instead. Her revenge involved switching bodies with Forbes before the movie, draining Dennis' bank accounts, and engineering the deadly game to destroy them.

Foreshadowing: Beatrice was institutionalized after the college incident and is never seen until the coda, making her sudden appearance at the wedding suspicious.

Beatrice is the true antagonist. Before the movie's events, she switched bodies with her brother Forbes at the mental hospital, hoping the mind swap would help her depression. Once in Forbes' body, she knocked him out, left the hospital, and spent months tracking the friends to orchestrate her revenge. The 'Forbes' at the party is actually Beatrice in Forbes' body, and she escapes in Nikki's body at the end.

Foreshadowing: The coda reveals Beatrice arrived at the wedding unexpectedly and the 'Forbes' speaking to her is actually Dennis in Forbes' body.

Shelby visits Cyrus to reveal her earlier proposal was a deliberate test. Before the final switch, she suggested they stay in Nikki's body and Reuben's body permanently and run away together, leaving Dennis to take the fall for the deaths. She wanted to see if Cyrus would abandon his body and responsibilities to be with her. When he agreed, she knew he didn't truly love her, so she's now content to let him rot in jail.

Foreshadowing: Shelby was in Nikki's body during Round Two and expressed jealousy over Nikki earlier in the film.

Beatrice escapes with the machine. During the final switch struggle, she took Nikki's body (sending Nikki into Reuben' body) and fled with the device. She also drained Dennis' bank accounts using information she obtained, making her wealthy and free in a completely new identity. She drives away into the sunset, untouchable.

Foreshadowing: The final switch was chaotic as police broke in, and Beatrice used the confusion to operate the machine.

During Round Two, Reuben (in Dennis' body) and Brooke (in Maya's body) discover they still have feelings for each other, Reuben was secretly attracted to Maya, and Brooke was in Maya's body. They confess their attraction, retreat to the rooftop, and have passionate sex. The balcony beneath them crumbles from the structural damage caused by the party, and both fall to their deaths.

Foreshadowing: The group earlier discussed the roof being dangerous and not properly maintained.

Dennis is in Cyrus' body during the chaos after Reuben and Brooke's deaths. Frightened and not realizing he's in Cyrus' body, Dennis panics and calls the police to confess to murdering their dead friends. He does this to get revenge on what he thinks is Cyrus' friends, not knowing he's actually incriminating himself since he's in Cyrus' body. This leads to Cyrus being charged with the murders.

Foreshadowing: Dennis was having a major freak out and accused Cyrus (who was actually in his body) of draining his bank account earlier.

Shelby proposed they permanently swap bodies, she would stay in Nikki's body and Cyrus would take Reuben's body, then run away together and leave Dennis trapped in Cyrus' original body to take the fall for the deaths. It was a test of whether Cyrus would abandon everything (his body, his friends, his responsibilities) to be with her. Cyrus agreed, proving to Shelby he would choose escape over loyalty.

Foreshadowing: Shelby operated the machine earlier and was excited to be in Nikki's body because she was jealous of her.

The final chaotic switch results in: Dennis is now in Forbes' body (and appears at the wedding as 'Forbes'), Maya is in Brooke's body, Nikki is in Reuben's body, and Beatrice is in Nikki's body having escaped. Forbes is stuck in Beatrice's body. Cyrus and Shelby returned to their own bodies, Cyrus in jail facing murder charges, Shelby visiting him. The exact final swap outcomes are confusing because Beatrice operated the machine during the police raid.

Foreshadowing: The final switch button was smashed during the struggle as police busted in, creating chaos.
