Wanted: Someone to go back in time with me. This is not a joke. You'll get paid after we get back. Must bring your own weapons. I have only done this once before. Safety not guaranteed.Jeff (Jake Johnson), a magazine writer in Seattle, sees the ad and convinces his boss (Mary Lynn Rajskub) to let him do a story about whoever placed it. Jeff takes along two interns, Darius (Aubrey Plaza) and Arnau (Karan Soni), as they track down the wannabe-time-traveler, Kenneth (Mark Duplass). Jeff can't gain Kenneth's confidence, but Darius does, and convinces him she wants to go along for the next ride back in time. As their relationship grows, we learn everyone's motives revolve around lost love.
