Scott (Michael Ealy) and Annie (Roxanne Avent) Howard move into their new house in Napa Valley, but its previous owner, Charlie Peck (Dennis Quaid), becomes obsessed with keeping an eye on the couple and ensuring his home remains untouched.
I found it an interesting role for Quaid who earlier played a documentary filmmaker Cooper Tilson in which he and his wife Leah had decided life in New York City had become unbearable, they and their children Kristen and Jesse move into a decaying mansion filled with the possessions of the previous family — in Cold Creek Manor (2003). The Intruder is somewhat a flip of that story with Quaid being the creepy guy who won’t leave.
Charlie, who claims to be moving to Florida, just keeps popping up - mowing the yard, complaining about the couple installing a security system and more.
Annie feels sorry for him.
Scott hates him.
The couple eventually learn Charlie had lived in the house with his wife Ellen and daughter Cassidy, but was deeply in debt and was forced to sell the house. They also learn that Charlie’s wife suicide might have been murder.
They know they must either flee or fight, and they are not about to leave their dream home.
