In the year 2010, Adam (John Cusack), Nick (Craig Robinson) and Lou (Rob Corddry) are three best friends living in Los Angeles, who have drifted apart from one another during the course of their lives. They all are disappointed in the way that they are living their lives now. Adam is getting dumped by yet another girlfriend, Nick is in a crappy job and his wife is cheating on him, while Lou is an alcoholic and hates everybody in his life. When Lou is admitted to the hospital for trying to commit suicide, which he vehemently denies, both Adam and Nick decide to relive their 80's in Kodiak Valley Ski Resort which were the best weekends of their lives. Jacob (Clark Duke), the nephew of Adam who happens to live in his uncle's basement, also gets dragged along to the K-Valley. But K-Valley is not what it used to be, it is now a run-down place which isn't that exciting. They go to The Great White Buffalo and are disappointed again to see the place in shambles. They get into the hot tub outside their room to relieve their stress and after a night of hardcore drinking, they find themselves transported back in time to 1986. They are worried that they would bump into their old selves, when they look at their reflections and see that they are their old selves. A weird old repairman tells them that they shouldn't change anything and do exactly the same thing that they did 20 years ago. Adam and Nick are in put in a quandry over this situation, while Lou thinks he can make this a profitable experience. But, can they get back to their lives in the present?
