Bad Milo is a horror comedy film that tells the story of Duncan, a man who is constantly stressed out by his job, his overbearing boss, and his dysfunctional family. One day, he starts experiencing severe stomach pains and discovers that he has a demon living inside his intestines. This demon, which he names Milo, emerges from his body to exact revenge on those who have caused Duncan stress and anxiety.
As Milo goes on a killing spree, Duncan must find a way to control him and prevent further chaos. With the help of a therapist, Duncan learns to confront his fears and insecurities, ultimately coming to terms with his inner demons.
Bad Milo is a darkly humorous take on the idea of repressed emotions manifesting as physical entities, and the importance of facing our fears in order to find peace and acceptance.
