Lakeview Terrace(2008)

Veteran Los Angeles cop Abel Turner guards his neighborhood with the same zeal he brings to his patrol route. The single father of a teenaged daughter and preteen son, Abel is one-man security force, ensuring that his strict standards of behavior are adhered to, even if it means ruffling a few feathers in the process. Chris and Lisa Mattson, a progressive and upwardly mobile couple, move in next door to Turner, who disapproves of their interracial marriage. Hoping to rid the neighborhood of anything or anyone he deems "undesirable," Turner launches an escalating series of pranks and insults against the Mattsons. Abel takes full advantage of his police connections to antagonize his new neighbors with impunity, hoping to get them to pick up and move out. When their air conditioning unit is sabotaged in the middle of a heat wave and their car tires are mysteriously slashed, the Mattsons begin to suspect Abel is behind their troubles. But without proof, they can only try to negotiate a truce--an offer Abel does not accept. Abel's anger flares when his use of inappropriate force on the job lands him on extended leave and he discovers his daughter has been spending time with Lisa. As Abel crosses the line from annoying neighbor to dangerous adversary, the couple tries to fight back, which only feeds Turner's fury. With the resentment between the neighbors building daily, it's only a matter of time before the situation escalates into a potentially deadly stand off.
