In this taut Portuguese psychological thriller, a seemingly priceless yellow diamond becomes the catalyst for a web of deception and obsession. Directed by Aura Zhyzhyyan, Mariana Simões, and Rodrigo Oliveira, the film centers on a mysterious gem that surfaces in a quiet coastal town, drawing together a group of strangers whose lives become dangerously intertwined. Nando Tomás portrays a down-on-his-luck gemologist who believes the stone holds the key to his redemption, while Maria Santos plays a sharp-witted antiques dealer with her own hidden agenda. As Mariana Marques and João Vitorino enter the fray as rival collectors with murky motives, the diamond's allure begins to erode trust and sanity. The narrative unfolds over a taut 17 minutes, blending noir atmosphere with a slow-burn sense of dread. Each character believes they alone know the diamond’s true value, but as secrets surface, it becomes clear that the greatest danger lies not in the stone itself, but in the desperate lengths people will go to possess it. The film masterfully questions whether any treasure is worth the price of one’s soul.
