On a stormy October day in 1968, eight strangers find themselves stranded in a remote bus station, their travel halted by impassable roads. As the tempest rages outside, a far more unsettling phenomenon begins inside: one by one, the travelers start to physically and mentally transform, becoming bizarrely similar to each other. Panic erupts as identities blur and paranoia takes hold, with each person desperate to retain their own mind and face while suspecting their fellow passengers. Directed by Isaac Ezban, this gripping sci-fi thriller features a tense ensemble including Gustavo Sanchez Parra, Carmen Beato, and Fernando Becerril as they confront a terrifying, inexplicable event. The film masterfully builds claustrophobic dread, exploring themes of identity and human nature under extreme duress, as the trapped group races to uncover the cause of the horrifying metamorphosis before they all become indistinguishable.
