Reversion

After moving with his parents to a new house in the suburbs, Mario, a sensitive and emotionally unstable teenager, tries to adapt to an unfamiliar environment while dealing with his anxiety episodes and the side effects of medication that clouds his mind. His only unconditional support is his older brother, David, with whom he shares a deep and protective bond. However, one rainy afternoon, everything changes: Mario helplessly witnesses strangers kidnapping David right before his eyes. From that moment on, his life turns into a nightmare of uncertainty, guilt, and despair.

For nineteen days, the family is consumed by anguish and waiting, until David finally reappears, confused, with no memory of his captivity. At first, everyone celebrates his return as a miracle, but Mario starts to notice small details that don't fit: differently gestures, cold looks, a strange way of speaking. The David who has returned seems to be someone else. No one believes Mario's suspicions, attributing them to his fragile mental state and the effects of his medication. However, the more he observes, the more convinced he becomes that something dark and terrifying lies behind his brother's return.

Obsessed with uncovering the truth, Mario plunges into a spiral of paranoia and fear, where the line between reality and his own delusions begins to blur. Is he losing his mind… or the person who returned is not really his brother?
