Eric devises a plan to secretly live in MrBeast's headquarters for 50 hours. He creates a fake Amazon truck and, with the help of his friend Beans disguised as a delivery driver, sneaks into the compound inside a box. Despite a close call at the gate, he successfully enters the main studio's warehouse through a forklift operation.

Eric disguises himself and begins exploring the vast MrBeast compound, which is significantly larger than previous places he's secretly lived. His friend Beans, holding a grudge against MrBeast for ruining his birthday, starts putting up posters of Eric's face on MrBeast's body around the office as a prank. Eric discovers various film sets, including a prison, a pool, a weight-loss challenge set, and a Minecraft house, considering them as potential sleeping spots.

Eric has a close encounter with contestants who become suspicious of him. Beans' posters escalate the risk of being caught. Eric orders 10 large pepperoni pizzas under Jimmy's name. While scouting for a sleeping spot, Eric accidentally walks into a room where MrBeast is watching a video, making eye contact before quickly retreating. Eric changes disguises and re-evaluates his strategy.

Eric contacts Mac, an editor for MrBeast, to confirm if anyone suspects his presence. Mac confirms MrBeast didn't recognize him in their previous encounter. Eric shares his order of 20 large pizzas under Jimmy's name, which Mac confirms were delivered. Eric asks Mac to secretly put him in a MrBeast video using pre-recorded footage. Beans' escalating pranks, including a massive poster on a video set, lead Eric to send him home to minimize risk, promising to ruin MrBeast's day for Beans.

Eric observes MrBeast heading to the paintball arena and considers sleeping in MrBeast's apartment. However, the lobby becomes unexpectedly busy. Eric decides to play it safe and sleeps in the Minecraft house. The next morning, he enjoys the quietness of the empty compound, takes a swim in the lake, and reflects on his unique living situation.

As employees return, Eric hides in the gym and gets a full workout in, discussing his upcoming boxing matches against other YouTubers. He then outlines his plan for the day: scout MrBeast's room, sneak into one of his YouTube videos, and finally sleep in MrBeast's bed. He anticipates a demanding schedule with shooting starting at 7 PM.

Eric narrowly avoids detection by suspicious contestants and successfully reaches MrBeast's apartment. He gives a detailed tour of the apartment, including the custom AI and a Feastables vending machine. To prank MrBeast for Beans, Eric orders 2,000 solo cups to build a large pyramid in the middle of the living room and leaves a taunting note.

While Eric is building the cup pyramid, he has to hide in the closet as someone enters the apartment. Shortly after, a friend calls to inform him that MrBeast is en route to his office. Eric quickly finishes the prank and makes his escape just as MrBeast arrives. MrBeast discovers the cup pyramid and poster, expressing bewilderment and annoyance, suspecting Eric.

Despite being seen by security, Eric proceeds with his plan to participate in MrBeast's paintball video as a guard. He learns that the contestants are competing for a $100,000 gold coin. During filming, Eric stands only inches away from MrBeast, who is meticulously directing the video and even comments on Eric's shoelaces. Eric successfully blends in, but eventually, contestants recognize him and start calling out his name, forcing him to flee mid-shoot.

After escaping the paintball set, Eric heads back to MrBeast's apartment and finally sleeps in his bed. He contemplates the possibility of MrBeast discovering him. The next morning, Eric successfully completes his 50-hour challenge without being caught. He walks out of the building without his disguise and takes a "victory lap," admitting his presence to various employees, who react with confusion. Finally, he drives away, ending his secret residency, and receives a series of confused and creeped-out texts from MrBeast.
