Motivational Growth is a film about Ian Folivor, a depressed and reclusive man who finds himself taking advice from a fungal growth after a failed suicide attempt. The Mold, a smooth talking chunk of aspergillus born from the filth collecting in Ian's neglected bathroom, works to win Ian's trust by helping him clean himself up and remodel his lifestyle. Ian attracts the attention of a neighbor, Leah, and begins to receive strange messages from his broken TV that make him realize that The Mold may not be as helpful and well intentioned as it seems to be.
