The story begins in the present day with three middle-aged friends: Adam, Lou, and Nick, who are each facing their own personal struggles and disappointments. To lift their spirits, Adam suggests they revisit Kodiak Valley, a ski resort they frequented in their youth.
Joined by Adam’s nerdy nephew Jacob, the group arrives at Kodiak Valley, only to find that it has become rundown and desolate. Disappointed by the state of the resort, the friends drown their sorrows in the hot tub outside their room.
During a drunken night of partying in the hot tub, the group accidentally spills an illegal Russian energy drink into the tub’s control panel, causing it to malfunction. The next morning, they wake up to find themselves transported back in time to 1986.
Confused and disoriented, Adam, Lou, Nick, and Jacob realize they have been given a chance to relive their glory days and correct their past mistakes. They set out to retrace their steps from the night before in hopes of understanding how they ended up in the past and finding a way back to the present.
As they navigate the 1980s landscape, the friends encounter various nostalgic references and cultural phenomena of the time. They also come face-to-face with their younger selves and interact with people from their past, including Adam’s former girlfriend, Jenny.
While attempting to blend in and avoid altering the timeline, the friends embark on a series of misadventures, including winning bets on sporting events, partying at an ’80s ski resort, and confronting their younger selves about their future.
However, their attempts to fix their past mistakes often backfire, leading to hilarious and unexpected consequences. Along the way, they learn valuable lessons about friendship, love, and the importance of living in the moment.
In the climax of the film, the friends realize that they must recreate the exact circumstances of their original hot tub experience in order to return to the present. With the help of their younger selves and Jacob’s knowledge of ’80s technology, they successfully activate the hot tub’s time-travel mechanism and return to the present day.
Back in the present, the friends reflect on their journey and the impact it has had on their lives. Despite their newfound appreciation for the past, they realize that their true happiness lies in the present and the friendships they have forged along the way.
