On their first day of high school, three best friends—Virgil Fox, Jason Dolley, Derek Beaugard, Steven R. McQueen, and Stephanie Jameson, Chelsea Kane—decide to push themselves with a variety of activities. Derek tries out for the football team, Stephanie goes for the cheerleading squad, and Virgil steps in to help when Charlie Tuttle, Luke Benward, interrupts football practice with a homemade rocket-powered vehicle. The moment ends in a public humiliation at the hands of the jocks, and afterward Virgil grows uneasy, resenting how that day unfolds and how it shapes the rest of their high school experience.
Three years pass, and the dynamics have shifted. Virgil and Charlie have become outcasts, while Derek and Stephanie have gained popularity and even entered a relationship. Amid this social upheaval, Charlie unveils a bold plan: he has built a time machine. He recruits another outcast, Zeke Thompson, Nicholas Braun, to lend his engineering know-how and to help bring the device to life. Once the trio tests the machine, their first voyage back in time leads them to a chance encounter with a local street performer, prompting them to convince him to buy a winning lottery ticket. The plan works in the moment, but they must return to the present early, which results in the performer ultimately winning the jackpot—a twist that prompts Charlie to rethink how they should use their new power.
To limit exposure and control the consequences, Charlie decides they should only use the time machine to undo key moments of pain from their classmates. He turns to Jeannette Pachelewski, Kara Crane, a classmate who quietly harbors an unrequited crush on Charlie, and asks her to oversee their excursions while the trio ventures into the past. Jeannette proves instrumental, even supplying snowsuits that shield them from the time stream’s freezing temperatures as a precaution against the unknowns of altered timelines.
The group earns a reputation as the “Snowsuit Guys,” a nickname that sticks even though they would prefer to be known as the Minutemen and be seen as heroes at school. Vice Principal Tolkan, J.P. Manoux, views their activities as troublemaking and keeps a close eye on them, adding a layer of pressure to their mission. As the trio continues to operate in the past, they begin to notice a troubling pattern: the bullied students of today are themselves turning into bullies in their own right, complicating their initial motivation to fix past hurts.
Complications mount when Charlie reveals that he has hacked into NASA’s files to secure the time machine’s technology. Realizing the potential fallout, he advises Zeke and Virgil to minimize their time-traveling. But Virgil breaks from the plan to protect Stephanie when she suffers a serious injury that could cost her a scholarship to her dream college, a choice that exposes his evolving feelings and pushes him to confront the ethical gray areas of their power.
The situation intensifies when Derek suffers a crushing loss at the state championship, prompting Virgil to try and repair the fractured friendship and help Derek reclaim his place. Yet the path to reconciliation is tangled, and Virgil’s loyalties are tested as he navigates his own growing feelings for Stephanie. The tension comes to a head when Stephanie uncovers Derek’s infidelity, a revelation that pushes Derek to seek Virgil’s help to avert it—and it forces Virgil to confront his own heart.
Behind the scenes, the FBI has been tracking the Minutemen’s activities. The investigation culminates in pressure that drives the trio to disband, driven by Virgil’s selfish decisions and the fear of exposure. After consulting with government scientists, Charlie learns that their time-traveling experiments have damaged the space-time continuum, creating a dangerous black hole that could endanger them all. With only hours left, the trio reunites to repair the damage by venturing into the black hole and returning to the earliest moment of their first journey.
Back on the first day of high school, they realize that no one remembers the Minutemen’s activities, a side effect of their tampering with time. Virgil confronts Derek about his treachery, and in a bid to restore order and secure his own future, Virgil and Zeke rejoin Charlie to re-enter the black hole as it closes. They are drawn back to the day they first time traveled, where they witness the present from the past and grapple with how to set things right without erasing the friendships that matter most.
As the timeline resolves, Virgil comes to terms with the complexities of friendship, loyalty, and courage. He reconciles with Charlie and Zeke, and together they step back from the brink, choosing to protect what matters most rather than pursue fame or heroism for its own sake. They return to the present, only to discover that the school’s memory of their exploits has faded, leaving them to redefine what it means to be brave. In the end, Charlie’s spark of invention remains, and he shares a renewed sense of possibility with Jeannette, who harbors her own quiet crush, while Virgil and Zeke carry Charlie away, supporting his dream of new, responsible breakthroughs like a future teleportation machine.
The story closes on a note of quiet hope, balancing humor with vulnerability, and underscoring the power of friendship when faced with tempting shortcuts. It is a tale about young people learning to navigate the consequences of their choices, the complexity of relationships, and the enduring value of genuine connection—even when the past keeps finding ways to catch up with them.
