After a devastating tragedy, Frank and Joe Hardy, together with their father Fenton, move to the small town of Bridgepoint to spend the summer with their Aunt Trudy. Their simple summer plans quickly come to an end when they discover their dad has taken on a secret investigation and Joe's life is threatened. Realizing that their Dad may be onto something, the boys take it upon themselves to start an investigation of their own.
When Fenton heads overseas to find Mrs. Khan's nephew, Rupert, he quickly realizes that whatever Rupert and Laura were working on garnered attention in Bridgeport. Meanwhile, Frank discovers an old note of his mom's in Bridgeport that mentions the sunken fishing boat and Joe and his new friend Biff befriend a man on the beach who asks them to help him by delivering a message.
Joe finds a strange golden idol hidden in his room, but when he accidentally breaks it, inside is a strange piece of broken stone that he stashes in his pocket. Later that day at the Bridgeport Fair Joe gets lucky, but he also draws the attention of the Tall Man. Meanwhile, Frank discovers some information about an old mining expedition that ended in tragedy and the boys start to wonder what their Mom was investigating.
When the thief's campsite is discovered, Joe is terrified that the toolbox he lent the man on the beach has been found by the police. Trying to hide his connection to the criminal, Joe enlists Biff to help him get his monogrammed soldering iron - that he kept in the toolbox - out of evidence at the police department. Frank confronts his grandmother after learning she had an argument with his mom.
Joe and Frank decode a message that leads them to try and make a drop at the warehouse, despite the fact the message was intercepted by Police Chief Ezra Collig. The drop goes awry, but later when the boys return looking for more clues, they find a piece of fabric that the person fleeing the warehouse left behind. When the Tall Man escapes from the hospital, the boys reveal their entire investigation to their friends and get their help to lure the Tall Man to Chet's farm.
Frank relents and takes the entrance exam to Rosegrave Preparatory School. Callie Shaw is also taking the test and the two become close as they work together to solve the exam's last escape room puzzle in Gloria's study. Unwittingly they discover a hidden door, marked by a similar symbol they've seen before. Meanwhile, when Joe finds out the Tall Man has escaped from jail, he quickly tries to find a safe place for his lucky charm.
Frank and Callie make a visit to Rosegrave Prep where Frank learns the Dean had a close connection to his mother... one the Dean feels unsafe discussing with Frank. Joe and Biff continue to investigate the scrap of fabric from the warehouse and make a discovery that leaves Biff conflicted. Mrs. Khan makes a play for the missing piece of The Eye by enlisting the Tall Man. However, things don't exactly go as planned when the Tall Man goes after Frank and Joe to get the missing piece.
Frank befriends Stacy, the new girl in town, after an accident. The Hardy boys start the school year in Bridgeport, since their dad is still away. Frank discovers his mom used to write for the high school paper and was investigating the most powerful families in Bridgeport... including the Estabrooks. J.B. Cox tries to put the squeeze on Joe to find out what he knows about The Eye, but Joe denies having what J.B. wants... his lucky charm.
When J.B. Cox offers Joe up to Gloria, he is hired to find the other two pieces of the Eye. Joe's lucky charm goes missing and Aunt Trudy uncovers the boys' investigation. Elsewhere, Fenton rescues Rupert Khan and learns what he and Laura were working on. Frank and Joe discover their mother's music box holds a secret.
After gaining access to George Estabrook's Secret Room, Frank and Joe take their great-grandfather's journal and maps to learn more about The Eye. Despite Frank warning them of danger, Joe and Biff strike out alone to find the Chamber of the Eye. Meanwhile, Callie grows increasingly suspicious and jealous of Stacy, upsetting Chet in the process. Frank confronts Stacy and discovers the truth behind her move to Bridgeport.
The town of Bridgeport is put under curfew with Joe and Biff missing. Frank realizes they must have gone looking for the Chamber of the Eye. When Frank asks Gloria for help finding the Chamber, Gloria doesn't know anything about an entrance to the old, sealed, mine tunnels so Frank must turn to Stacy for help. Frank lets Officer Jesse Hooper in on their investigation, and the boys find themselves in more danger than they'd expected.
Frank has no choice but to side with his grandmother and play her game if he wants to get close enough to destroy The Eye. Fenton returns to Bridgeport with Rupert Khan and learns that Joe and Frank have gotten themselves farther along in their investigation than he could imagine. But when Fenton tries to get Frank to leave the Estabrook Estate, his son refuses. Spurned by Frank, a revenge-seeking Stacy puts one of Frank's friends in danger.
Frank and Chet find a way to rescue their friend without giving up the Estabrook piece of The Eye to Stacy, while Joe, Biff and Phil break into the Estabrook Estate looking for the missing piece, but they're too late. With Fenton's help, the Hardy boys will have to find their way to the hidden Chamber to stop the Circle from reuniting the Eye. What happens next changes everything for them.
