Kate Conklin (Gillian Jacobs)'s new book isn't selling well, so when her former professor and old crush (Jemaine Clement) invites her to return and speak at her alma mater, she agrees. Following her talk, he asks her to stay and teach. While taking photos of the house where she used to live, she meets a group of 20-year olds who ask her to a party, which makes her feel young again.
