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 stores night security guard is murdered. The local police have no leads, and show no interest in investigating further. Determined to find the killer and bring him to justice, Evan decides to form a neighborhood watch. However, he only manages to recruit Bob Vince Vaughn, a construction worker and loving father Franklin Jonah Hill, a high school dropout who dreams of being a police officer but failed the written, physical, and mentalhealth tests and Jamarcus Richard Ayoade, a recent divorc.The watch members use the group as an excuse to drink and have fun much to Evans annoyance. While driving on patrol, they accidentally hit something. They discover a strange metallic orb that acts as a highlydestructive weapon, and deduce that it is of alien origin. Meanwhile, several more townspeople are mysteriously killed. The watch responds to the murders and encounters an alien, which attacks them. Evan apparently kills it with a lawn gnome before the group returns with the creature to Bobs house. The creature regains consciousness and escapes, stealing the metallic orb and warning them that the aliens have already infiltrated the town. The watch theorizes that the aliens are stealing their victims skin and disguising themselves as humans, so anyone in Glenview could be an alien. 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 to her may cause her to leave. ........
