Insidious

Married couple Josh and Renai Lambert, their sons Dalton and Foster, and infant daughter Cali, have recently moved into a new home. One night, Dalton is drawn to the attic and frightened by something in the shadows. The next day, he falls into an inexplicable coma.

After three months of treatment without result, Renai and Josh are allowed to take Dalton home. Soon after, paranormal activity begins to occur; Renai begins hearing voices over the baby monitor when no one is in Cali's room, Foster says that Dalton sleepwalks at night, Renai sees a frightening figure of a man in Cali's room, and the home's security alarm is repeatedly triggered for no reason. After Renai finds a bloody hand print on Dalton's bed, she questions Josh about the house, but he ignores her. That night, Renai is attacked by the figure from Cali's room, and the Lamberts decide to abandon the house and move elsewhere.
