Gouache is a psychological thrilledy that follows Trey, a drifting painter and martial artist who tells his journalist friend Rochelle about helping a troubled man named Emilio recover from a breakdown. As she listens, small inconsistencies in his story begin to surface, leading her to question what is real. When Rochelle finally pieces together the truth, she discovers that Emilio may never have existed and that Trey has been living inside a version of himself he can no longer recognize. The film blends grounded realism with subtle surreal visuals inspired by Cubist fragmentation and the layered qualities of the gouache medium. Its cinematography, sound design, and narrative structure mirror the disorientation of dissociation while challenging stigma around mental health. Gouache explores identity, trauma, and self acceptance, inviting audiences to witness a mind struggling to hold itself together and the compassion required to truly understand it.
