Once a legend in the brutal world of illicit underground fighting, Shane Slavin (Daniels) decides to turn his life around, promising his wife and young son he's fought his last battle. But when his younger brother betrays a ruthless crime boss (Weller), Shane is forced back into the arena to pay his brother's debts and to protect his family.

INNER DEMONS follows an 'Intervention'-style reality show crew that films an episode about a sixteen-year old girl, a former A-student, who is fighting addiction but may in fact be suffering from something even more destructive: demonic possession. The movie is an inquiry into the truth about her - with symptoms that straddle the disturbing and scary intersection between insanity, addiction and true possession.
