Happy Death Day

The film opens on Monday, the 18th, as Teresa 'Tree' Gelbman celebrates her birthday. She awakes in the dorm room of her classmate Carter Davis, feeling disoriented and groggy.

As Tree stumbles through her morning, she has an uncomfortable encounter with Carter's roommate Ryan. He jokes about their night together, leaving Tree feeling disgusted and embarrassed.

On her way back to her room, Tree faces Tim, a guy she had previously dated. His accusation about being ignored reminds her of their disappointing Subway outing, prompting her to dismiss him.

Upon returning to her room, Tree’s roommate Lori surprises her with a homemade cupcake. Tree shows her disdain by blowing out the candle and tossing the treat into the trash due to her carb concerns.

Later, Tree attends class and engages in a secret affair with her married professor, Gregory Butler. Tension mounts as their relationship threatens to lead to complicated consequences.

During a lunch meeting with her sorority sisters, Tree witnesses Danielle reprimanding a sister for bringing junk food. This showcases the social dynamics and pressures within the sorority.

As the day progresses, Tree encounters a mysterious figure wearing a baby mask. In a shocking turn of events, she is stabbed to death by the masked killer, ending her birthday in horror.

Tree wakes up again in Carter's room, realizing she is trapped in a time loop. Each time she attempts to change her fate, she finds herself meeting the same gruesome end.

With each iteration of the day, Tree becomes increasingly frantic to identify the killer behind her murders. She starts narrowing down her list of suspects, including Tim, Danielle, and Gregory.

After witnessing the murder of her professor, Tree believes serial killer Joseph Tombs is the mastermind behind the chaos. She prepares for a confrontation with him, seeking closure.

In a tense climax, Tree confronts Joseph Tombs after multiple narrow escapes. Despite the high stakes, she manages to overpower him, momentarily breaking the deadly cycle.

In a final twist, Tree learns she was poisoned by a cupcake from Lori, which led to her original death. Lori's jealousy becomes the catalyst for her deadly schemes, revealing the true antagonist.

A climactic battle ensues between Tree and her roommate Lori. Tree fights back against Lori’s betrayal, ultimately overcoming her in a fierce struggle for survival.

The film concludes with Tree and Carter at a diner, reflecting on their wild experiences. They share a moment of laughter and intimacy, symbolizing a fresh start after chaos.

Carter playfully hints at the end of the loop when he reveals it’s Tuesday, the 19th. Their shared moments after the trials suggest hope and resilience as Tree smiles onto a new chapter.
