Imaginary Heroes (2005)

Following a sobering family tragedy, the Travises go to pieces. Teenaged son Tim, the black sheep of the family, walks through his life like it’s a bad dream. His father Ben begins treating his wife and children like strangers and completely disengages from the world around him, while his mother Sandy takes to smoking pot and letting loose with all the considerable sarcasm she can muster. Meanwhile, she wages a bitter feud with the next-door neighbor over carefully concealed secrets that threaten to tear the family apart.
