My review of Gabriel Martins’ *On Behalf of My Son* (*Vicentina Pede Desculpas*), an extraordinarily moving Brazilian drama about grief, responsibility, and the limits of forgiveness. Featuring a remarkable performance by Rejane Faria, the film follows a mother who travels across the city to apologize to families devastated by her son’s actions. Through intimate encounters, restrained performances, and a striking contrast between urban noise and personal suffering, Martins creates a powerful meditation on guilt, human connection, and the impossibility of repairing certain tragedies. Premiering at TIFF 2026, the film transforms the simple act of asking forgiveness into an emotionally profound cinematic experience.
