What Happens at the End of I Know What You Did Last Summer?

How I Know What You Did Last Summer (2025) ends, what the final scene means, which earlier moments set it up and how to read the ending if the film leaves it open. The full ending explained, with every spoiler.

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.

I Know What You Did Last Summer Ending: Your Questions Answered

The questions people ask most about the ending of I Know What You Did Last Summer (2025): what the final scene means, how the twist works, what happens to each character and how to read the ending. Each answer contains spoilers.

Q1

Who are the two killers behind the Fisherman attacks?

The Fisherman is actually two people working together: Stevie and Ray. Stevie, grieving her boyfriend Sam's death, becomes the Fisherman to exact revenge on the friends she blames for ignoring her loss. Ray, revealed during the climax, has been secretly acting as one of the Fishermen to cover up Southport's violent history and reshape the town's image.

Foreshadowing: Earlier scenes show Stevie's emotional withdrawal and Ray's suspiciously convenient knowledge of the killings.

  • fisherman killer
  • stevie
  • ray
  • dual killers
  • who is the fisherman
Q2

Why does Stevie become the Fisherman and target her friends?

Stevie transforms into the Fisherman because of grief and rage over her boyfriend Sam's death in a car accident. She believed her friends had ignored or dismissed Sam's death, so she took justice into her own hands. The twist is that Stevie was actually responsible for Sam's death herself, making her quest for vengeance a way to project her own guilt onto others.

Foreshadowing: Stevie's emotional distance and frequent references to Sam hint at unresolved trauma.

  • stevie motive
  • revenge
  • sam death
  • grief
  • why killer
Q3

What is Ray's motivation for being one of the Fishermen?

Ray's motivation stems from a desire to protect Southport's image by eliminating what he sees as violent threats to the town. He believes he's reshaping the town's legacy by removing people connected to past crimes. His revelation that he was one of the killers shocks everyone, especially when he questions whether he actually shot Stevie, showing his manipulation extends even to his own actions.

  • ray motive
  • southport
  • cover up
  • town image
Q4

Does Stevie survive after falling into the ocean?

Stevie appears to survive her fall into the ocean. After Ray shoots her and she falls into the water during the boat chase, the film hints she could return by showing her washing up ashore alive at the end. This ambiguity leaves the door open for potential sequels, suggesting Stevie may appear again in future installments.

Foreshadowing: The film deliberately avoids showing Stevie's death, keeping her fate uncertain.

  • stevie survives
  • ocean
  • falls
  • ending sequel
Q5

How does Ava stop Ray in the final confrontation?

Ava stops Ray by shooting him with his own speargun during the climactic boat chase. When Ray tries to kill Danica and reveals his darker intentions, Ava uses the speargun to shoot Ray, saving Danica from further harm. This act marks Ava's transformation from victim to survivor who takes decisive action to end the threat.

Q6

Danica eventually washes up ashore alive, escaping the life-or-death situation along with Ava. Both main characters make it out alive, though the experience leaves them forever changed.

Foreshadowing: Danica's survival is set up through her resilient characterization throughout the film.

  • danica survives
  • boat chase
  • injury
  • lives
Q7

Why does Ray question whether he actually shot Stevie?

Ray's questioning of whether he actually shot Stevie reveals his manipulative and duplicitous nature. Even in the moment of confrontation, Ray attempts to control the narrative and confuse those around him. This moment highlights how calculated and deceptive Ray has been throughout the film, as he tries to make everyone question the truth even as he's exposed as a killer.

  • ray shoots stevie
  • manipulation
  • question
  • truth
Q8

What does the ending scene with Julie and Karla imply?

The ending scene shows Julie consulting Karla, the heroine from the previous I Know What You Did Last Summer films, to prepare for future threats.

The filmmakers are clearly setting up potential sequel hooks, leaving the story on a tense, uncertain note while connecting the new film to the franchise's legacy.

Q9

What does the Fisherman's mask and identity represent thematically?

The Fisherman's mask represents hidden guilt and the consequences of secrets. The dual identity of the Fisherman, Stevie and Ray, both driven by their own traumatic experiences with death and violence, symbolizes how past actions cast long shadows. The mask allows them to become executioners while hiding from their own humanity, exploring themes of justice, revenge, and the blurry lines between victim and perpetrator.

Foreshadowing: The recurring imagery of the Fisherman throughout the film builds the thematic weight of hidden identities.

  • fisherman mask
  • symbolism
  • hidden identity
  • revenge
  • justice
Q10

Does the film set up a sequel and what does the ending suggest about future stories?

The ending clearly sets up a sequel by showing Julie seeking help from Karla and hinting at Stevie's potential survival. The unresolved nature of the story, Stevie possibly alive, the cycle of violence continuing, indicates the filmmakers intend to continue the franchise. The ambiguous ending leaves multiple threads open: Stevie's fate, the ongoing threat, and how Karla might factor into future confrontations.
