STAIN follows Ishaan, a man in a disturbed mental state, obsessively trying to wash what appears to be blood off his hands. The situation suggests something violent has just occurred, but the details remain unclear. As he spirals deeper into panic and confusion, a stranger named Vikram enters his space. What begins as a simple interaction, turns into a tense psychological exchange. Through their conversation, fragments of Ishaan’s past begin to surface—hinting at a traumatic incident tied to fear, guilt, and a moment that changed everything. As the tension builds, the film shifts from a physical mystery to a psychological one, forcing the audience to question what really happened—and what truly haunts Ishaan.
