Fueled by energy drinks, vodka and nostalgia for their younger, wilder days, a group of aging best friends travels back in time to 1986, where they get the chance to relive the best year of their lives. And their time machine? Well, it's a hot tub. John Cusack, Rob Corddry, Craig Robinson, Clark Duke, Crispin Glover and Sebastian Stan co-star in this out-of-the-box comedy that takes time travel to a whole new level.
