In the town of Glenview, Ohio, Evan Trautwig (Ben Stiller) is an active participant in the community and senior manager of the local Costco store. His life is disrupted when the store's night security guard is murdered. The local police have no leads, and show no interest in investigating further.

Bob confides to Evan that he is worried about his daughter Chelsea (Erin Moriarty), and does not trust her boyfriend Jason (Nicholas Braun). Evan admits that he has been avoiding his wife Abby (Rosemarie DeWitt) because he is infertile, and revealing that it may cause her to leave.Evan suspects that one of his neighbors is an alien (due to his strange, stiff way of speaking and because he always seems to be watching him). As the watch scouts the neighbor's house, Bob learns that Chelsea is at an unsupervised party with Jason. Bob disobeys Evan's...
