Three years after the events of the first film, Lenny Feder has relocated his family to his hometown of Stanton, where his friends Eric Lamonsoff, Kurt McKenzie, and Marcus Higgins also live. Lenny wakes up in his bedroom to find a deer which wreaks havoc through the house until he uses his daughter Becky’s stuffed animal, Mr. Gigglesworth, to lure it outside, where it tears him apart. Lenny dismisses his wife Roxanne’s suggestion that they have another child; Eric worries that his wife Sally is encouraging their children’s self-confidence above all else; Kurt gives his wife Deanne a gift for their anniversary, which she has forgotten; and Marcus prepares to spend the summer with Braden, his recently discovered son from one of his previous relationships, but is intimidated by Braden, who deeply hates him.
