On the morning of September 11, 1973, Andrés Salazar jolts awake alone in a Santiago radio station, moments before tanks descend on the city. The broadcast has ended in static. The building is abandoned. And outside, the coup has already begun. Each time he tries to escape, time resets. Each loop reveals new clues—voices that shouldn’t exist, erased names, and echoes of a woman who may not be real. Andrés knows something is wrong with the memory of that day. But the more he tries to warn others, the more the signal fights back. As Andrés digs deeper, the boundaries between history and repetition begin to unravel. Who is really listening? Why is the signal alive? And why does silence feel more dangerous than the truth? Set against the haunting backdrop of Chile’s fractured past, Loop 1973 is a tense, psychologically charged descent into memory, guilt, and the architecture of time. If a man keeps broadcasting into a world that’s forgotten him, is he preserving history—or becoming part of its trap?
