Smother(2008)

Marilyn Cooper is one of those mothers--the kind who'll call at 6:30 in the morning, or tell embarrassing stories about her son Noah to complete strangers. When she suspects her husband is having an affair, she decides it's time to "take a break," and shows up on Noah's doorstep with bags and five foster dogs in tow. Already having lost his job, hosting an unwelcome houseguest on his couch, and facing pressure from his wife Clare to start a family despite his fears of inadequacy, Noah now finds the mother he's always kept at a distance just a room away. He soon starts to realize that if he wants to stand up to the problems in his life, he'll have to stand up to his mother.
