Bad Milo!

Duncan, a man stuck in a dull job and weighed down by pressure from his family, starts suffering from severe intestinal pain. The cause turns out to be a creature living inside him, one that grows stronger under stress and emerges to lash out at the people around him. His psychologist, Highsmith, offers an unusual diagnosis: the being is a physical manifestation of Duncan's anxiety, and the way to deal with it is not to fight it but to accept it. Duncan gives the demon a name, Milo, and tries to keep his life and his loved ones safe while managing both the creature and his own tension.
