In Pasadena, friends Costa and J.B. decide to throw a birthday bash for their buddy Thomas. With Thomas's parents leaving for the weekend, they aim to make it unforgettable, despite Thomas's apprehensions about the guest list and his father's car.

Thomas, although hesitant, invites Alexis, the most desirable girl in school, along with his close friend Kirby. Unknown to Thomas, Kirby secretly has feelings for him, adding tension to the invite.

To document their chaotic night, Costa hires Dax, an aspiring filmmaker. This decision sets the stage for capturing the wild antics that are about to unfold.

Costa and J.B. embark on a mission to procure marijuana from T-Rick, an unreliable drug dealer. During the encounter, Costa mischievously steals a quirky lawn gnome, leading to a frantic escape.

As the planned start time for the party approaches, Thomas grows anxious when no guests arrive. Just as he fears a flop, hundreds of party-goers flood his backyard, igniting a wild celebration.

To maintain order during the festivities, Thomas employs security guards, Everett and Tyler. Despite his efforts, Costa's reckless marketing campaign stirs up more chaos than anticipated.

The party takes a drastic turn when T-Rick's gnome unexpectedly reveals hidden ecstasy tablets. This discovery propels the wild night into a frenzy as party-goers indulge without reservations.

When the police respond to a noise complaint, the party-goers cleverly feign innocence. Their act succeeds, and the officers leave, allowing the revelry to continue uninterrupted.

In a poignant moment, Thomas confesses his love to Kirby with a kiss, while Alexis flirts with him too. This romance complicates the dynamics when Kirby catches them, leading to her heartbreak.

The scaling party atmosphere catches the attention of news helicopters overhead, broadcasting the nighttime madness to the world. The event spirals further out of control as more guests join in on the fun.

In a moment of audacity, a dwarf guest drives Thomas’s father’s Mercedes straight into the pool. This adds yet another layer of chaos to the already wild party, shocking everyone present.

T-Rick confronts the revelers with a flamethrower, desperately seeking retaliation for the theft of his gnome. His entrance incites panic and causes chaos as flames threaten to engulf nearby cars and trees.

As the police arrive in large numbers, they struggle to regain control over the explosive situation. The party ultimately culminates in a hurried escape for Thomas, Costa, J.B., Dax, and the rest of the guests.

The following morning, the group returns home, facing the reality of their chaotic night. Thomas's father is unknowingly impressed, yet imposes stern consequences on his son by using his college fund to pay for the damages.

In a surprising twist, it’s revealed that T-Rick survived the inferno. Meanwhile, Thomas deals with legal troubles while Costa and J.B. escape serious repercussions, setting the stage for future escapades.
