The film opens on Walton Island, a property formerly owned by World War II veteran, Alexander Walton. When Alexander mysteriously disappears, his family loses control over the island. Enter Andy Walton, a talented swimmer and high school student, who has a younger brother, Mark, a bright kid battling a severe ear condition. Unfortunately, Andy’s dreams of swimming scholarships are dashed when he faces defeat in a critical contest, leading him to make poor decisions that include stealing drinks from a store, compounded by feeling abandoned by his so-called friends.

Subsequently, to impart some discipline, their parents decide to send Andy and Mark to stay with their Uncle Trent, a relative they have never met before. During this transition, Andy discovers a pocket watch, an item that becomes significant later on.

Upon arriving at the island, Uncle Trent introduces them to the once-thriving West Forest, rumored to be haunted due to the chilling deaths of nine individuals. While there, Andy reconnects with Claire, a friend he likes. As the story unfolds, the boys learn about a hidden treasure their grandfather bequeathed to the family, igniting Andy’s fervent interest.

One evening while dining with Claire’s father, John Broman, who is the island’s current owner, Andy learns of a shocking turn of events: Uncle Trent lost their family home to John during a poker game, which fuels his anger. Tensions mount as Andy nearly meets with disaster when someone attempts to shoot him in the West Forest. Heeding Trent’s strict warning about the dangers of the forest serves only to intensify their curiosity.

As the plot thickens, Andy and Mark stumble upon another pocket watch alongside Trent, which contains messages from Alexander that they believe might lead to the treasure. Driven by excitement, they venture to the beach at midnight, particularly after a confrontation with Trent fueled by his alcoholism. The following day, their friendship deepens when Claire admits her feelings for Andy, culminating in a kiss. He gives her a necklace, marking a tender moment, and in return, she gifts a chain with a key to Mark.

While exploring, Mark’s discoveries lead them to a lighthouse, after which they find more clues that ultimately guide them to the Broman house, where remnants of Alexander’s possessions are safeguarded. In a clever ruse, Claire helps the boys retrieve a key from her father, unveiling John’s dark involvement in the deaths of the nine people.

Amidst their reckoning, they stumble into a secret room filled with ancient mysteries, where they unearth a key and a device. Upon returning home, they confront the intoxicated Trent, whom Andy discovers is his father—prompting a furious exit while Mark stays behind. Concerned for Andy, Trent and his companion, Jim, set out to locate him.

Venturing into the ominous West Forest, Andy discovers an underground passageway that soon becomes sealed. With the aid of a walkie-talkie, Mark finds his brother, and together they unlock a door using Claire’s keychain, revealing a hidden gold mine. The stakes rise dangerously when John appears, brandishing a gun and confessing to the tragedies that befell their grandfather.

As the brothers navigate the perilous mine, they face a life-threatening encounter where John pushes Mark into the turbulent sea, but Andy retaliates by pushing John. Fortunately, Jim and Trent arrive just in time to rescue them from drowning, while John meets his fate. As the dust settles, Claire departs from the island, and a heartfelt reconciliation occurs among Andy, Trent, and the Waltons, closing a tumultuous chapter of their lives.
