Director and star Louise Weard plays Michaela 'Traps' Sinclair, a trans sex worker in Vancouver who mentors her recently-out trans friend Adeline, pursues motherhood via temporary detransition and sperm donation at a fertility clinic, and navigates relationships including with a 'chaser' boyfriend. This is juxtaposed against the parallel chapter 'Incel Superman,' where cis production assistant Turner Stewart spirals into 4chan incel culture, misogyny, and self-destruction as his relationship collapses.

The title 'Castration Movie' and explicit scenes of orchiectomy aftermath, unsimulated sex, and body-focused elements foreground gender ideology as the narrative engine. Creator Louise Weard's stated intent to craft 'a trans story by us, for us, and about us' and 'cinema by, for and about trans people' makes the progressive framing foundational rather than incidental. The identity-driven arcs of mentorship and detransition motherhood, paired with the incel subplot as an explicit foil, turn the work into a platform for ideological contrast. This heavy-handed approach functions as a negative intrusion that crowds out neutral storytelling and compromises entertainment value by subordinating character and plot to activist messaging.
