The bad vibes begin when Chris (Patrick Wilson) and Lisa Mattson (Kerry Washington) move in next door to widowed cop Abel Turner (Samuel L. Jackson, as nasty as Aaron Eckhart in LaBute's In the Company of Men). A strict father of two, Turner works in a diverse unit (Jay Hernandez plays his partner), but takes less kindly to interracial relationships. From the start, he makes the Mattsons uncomfortable with inappropriate remarks and unwarranted intrusions, like the security light trained on their bedroom, under the guise of self-appointed neighborhood guardian. Initially, Turner's actions exacerbate the tensions between the seemingly happy pair--Lisa wants to start a family, Chris wants to wait--until they realize they'll have to work together to protect themselves from their troubled neighbor. And since he's a member of the LAPD, Turner's colleagues have his back, despite the break-ins and flat tires bedeviling the Mattsons. When they make it clear they intend to stay, Turner takes his harassment campaign to the next level.
