Maria: "Yo... no sé cómo explicar. Anoche, cerca del festival de la manzana, vi algo terrible. Mi cámara... la grabó. No debería haber estado allí." Hunter: "Slow down. I’m Detective Hunter. I need to know what you saw at the festival." Maria: "Yo no hablo inglés... pero había una luz, y luego alguien gritó. Después, silencio. Y la gente... desapareció. Estoy asustada." Hunter: "I’m sorry, I don’t understand Spanish. Did you say someone disappeared?" Maria: "Sí. Desapareció. Una mujer, creo... llevaba un abrigo rojo. Yo estaba tomando fotos del paisaje, y entonces... todo cambió." Hunter: "Red coat. Got it. Where exactly were you standing?" Maria: "Allí, cerca de los árboles. La cámara estaba apuntando al río. No miré a tiempo. No miré a tiempo..." Hunter: "You look shaken. Did you see a vehicle? A face? Anything I can use?" Maria: "No vi bien. Solo oí pasos, muy rápidos. Y después... miedo. Mucho miedo." Hunter: "This town keeps getting stranger by the day." Maria: "Mi cámara... tal vez tiene la imagen. Pero yo no quiero verla sola." Hunter: "I need that camera, but I can’t stay here and sort this out right now—" Hunter: "—That’s my phone. I have to go. Don’t leave town, and keep that camera with you." Maria: "¿Irse? No... espere—"
