In the six-part series, Kieran Elliott and Mia Chang go back to Evelyn Bay on the 15th anniversary of a storm that killed three people. The people in Kieran's town never forgave him because they thought he had killed his brother Finn and friend Toby. At the same time, the disappearance of Gabby Birch was buried under a blanket of silence.

When Bronte comes to find out the truth about Gabby, she walks into the same darkness that consumed the past by accident. Sean Gilroy kills Bronte to silence her because he feels guilty and scared.

Ad

The story is about Kieran's emotional struggle with his past, Mia's search for answers, and Evelyn Bay's toxic culture finally being shown for what it is.

The show doesn't just solve murder mysteries; it also looks at grief, traumatic events that happen across generations, and a broken masculinity, building up to a spooky ending where responsibility is finally given its due.

The last episode of The Survivors starts with a scary confrontation in the caves, which are the same caves where the tragedy happened 15 years ago. From this point on, the fight is between Kieran and Sean. Keiran knows Sean was hiding something when Mia tells him that Gabby's name is carved deep in the caves. He asks Sean to come back to the site under the guise of looking into where Gabby was last seen.

As Kieran and Sean go deeper into the watery caverns, more information comes to light. Sean finally admits to his crimes when Kieran keeps asking him about it and knows everything about it. Gabby was tricked into thinking Kieran would be in the caves by Sean years ago. Sean then took her there. When Gabby turned down Sean's romantic proposal, he lashed out and left her to the waves.

He shut down anyone who told the truth because he didn't want to face the consequences of what he did and failed to save her.

Bronte became the second person Sean killed. She accidentally finds Gabby's name carved into the cave walls, which makes Sean feel guilty. When she told him about her findings and the art tribute she wanted to make, Sean became scared.

He hit Bronte and dumped her body in the ocean because he was afraid of being caught. Brian desperately tries to save Bronte by giving her CPR, but it doesn't work. Sean put Bronte's camera in the shed behind Kieran's house and wrote "perv" on the doors to make it official.

Ad

This was done because all of Sean's DNA was on Bronte. He even scratched Gabby's name off the cave walls so no one would know she was there with him.

Finn, Toby, and Gabby were killed in the terrible storm that sets the scene for the backstory of The Survivors. That terrible night, Finn and Toby went out to sea to try to save Kieran, who had gone into the caves even though there were storm warnings.

Ad

They never came back, and the people of the town will always remember and honor their sacrifice as heroes. The death of Gabby Birch, which happened on the same night, is, however, mostly forgotten.

The first episode of the series looks at how the town remembers its dead in an unfair way. Gabby's disappearance from public view seems to be missing from the attention paid to Finn and Toby's brave actions.

When Gabby goes missing for no reason, Bronte goes to Evelyn Bay to look for answers. However, she hardly had any idea that this search would end in her untimely death.


Kieran’s guilt and Brian’s silent sacrifice

In The Survivors, Kieran's long-buried guilt and the emotional sacrifices his father, Brian, made are at the heart of the story. On the 15th anniversary of the storm, Kieran's return to Evelyn Bay forces him to face the wounds from his past that haven't healed. People blamed him for the deaths of his brother Finn and their friend Toby since they thought Kieran's choice to explore the caves led to the terrible events.

Ad

Over the years, Kieran kept this guilt inside himself and thought he was to blame for the deaths and the pain his family went through. But when Kieran admits that he wasn't the one who called for help, a big secret is revealed. Gabby's sister Olivia, not Kieran, was the one who called Finn and Toby.

Kieran feels guilty, and Brian makes a quiet sacrifice. After Finn died, Brian told Kieran to leave Evelyn Bay because he was afraid that Verity's anger would destroy him. Brian couldn't deal with the heavy emotional weight of his wife's grief, so he sent his son away to protect him from more pain.

Even though it was done out of love, this sacrifice hurt Kieran's heart and made him feel sad and alone for years.


Verity, Julian, and their silence

The Survivors explores how silence and denial are perpetuated by the two key figures in Evelyn Bay: Verity, Kieran’s mother, and Julian, Toby’s father. For 15 years, Verity has stuck to the idea that Kieran killed Finn and Toby, even though it's possible that Kieran wasn't directly responsible.

Ad

Verity's refusal to accept the truth about Olivia's part in the terrible event comes from her deep sadness. It's too painful for her to think that Finn's death might not have been Kieran's fault, so she sticks to her story. She was mean to Kieran because she couldn't deal with her grief and process her loss. But Julian's part is to actively help with the crime.

Julian has been involved in the cover-up surrounding Gabby's death. He cares a lot about keeping the happy memories of his son Toby alive. He hid the truth, especially when he threw away Gabby's bag, which was found on the boat.

Ad

People in Evelyn Bay don't just stay quiet because they're passive; those in power, like Verity and Julian, choose to do so in order to keep telling the story of Finn and Toby's bravery and hide the truth about Gabby's death.


False leads and a town of secrets

The Survivors keeps viewers guessing about who might have killed Bronte. Barlin, the local author with a troubled past, is one of the most important parts.

Ad

Barlin was once accused of s*xual harassment, and when it comes out that Bronte had been seeing him, he becomes a suspect. He also helps Bronte with her art project and sets up a darkroom at his house for her.

But it turns out that Barlin was seeing someone else when Bronte died, which clears him of any wrongdoing in her death.

Julian, who is seen in a heated argument with Bronte not long before she dies, is another suspect. Since Bronte was getting too close to the truth in her investigation into Gabby's death, his anger toward her could be seen as a reason to kill her.

Ad

Julian's role in covering up Gabby's death was his way to protect his son, not intending to hurt an innocent woman.
