I Know What You Did Last Summer (2025) – Ending Explained & Final Scene Breakdown

Still thinking about how I Know What You Did Last Summer (2025) ended? Here’s a full breakdown of the ending, key final moments, major twists, and the deeper meaning behind the film’s conclusion.

The ending of I Know What You Did Last Summer reveals a twist-filled confrontation where the characters discover that the killer isn’t just one person, but actually two: Ray and Stevie. Throughout the film, the friends are targeted by a masked fisherman seeking revenge for a past accident they thought they had covered up. As the story unfolds, it’s revealed that Stevie’s motive for becoming the Fisherman stems from her grief and rage over her boyfriend Sam’s death in an earlier car accident, which she mistakenly thought her friends had ignored or dismissed. Her emotional trauma motivated her to take justice into her own hands, transforming into the murderer to exact her revenge.

Stevie’s betrayal comes to light when she reveals during a tense boat chase that her supposed disconnection from the past isn’t true—she was the one responsible for Sam’s death, and her quest for vengeance has made her murderous. When Ray arrives on a smaller boat to help, Stevie stabs Danica, leading to a confrontation where Ray shoots her, causing her to fall into the ocean. However, the truth about Ray is even darker: he, along with Stevie, has been secretly acting as one of the Fishermen, driven by a desire to cover up Southport’s violent history and to reshape the town’s image. Ray’s revelation that he was one of the killers shocks everyone, especially since he tries to manipulate Ava and even questions if he truly shot Stevie.

The climax concludes with Ava shooting Ray with his own speargun to stop him, saving Danica from further harm. Ava and Danica survive, with Danica washing up ashore alive and Stevie apparently surviving her fall into the ocean as well, hinting they could appear again. The film ends with a scene showing Julie consulting Karla, the heroine from the previous films, to prepare for future threats, suggesting that the cycle of terror might not be over. The filmmakers leave the possibility open for another sequel, depending on the audience’s reaction, leaving the story on a tense and uncertain note.
