Insidious

Patrick Wilson and Rose Byrne star in this creepy, psychological horror about a series of inexplicable events that take place after a couple's young son falls into a coma. Renai and Josh Lambert have recently moved into a new home with their son Dalton. One day, Dalton is playing in the attic when he sees something that terrifies him - and the next day, Josh and Renai can't wake him up. They're told he's fallen into a sudden coma, but the cause is a mystery. Three months later, they move him back into the house, still in the coma, and within days a number of strange happenings take place. A bloody handprint appears on Dalton's bedsheets. Renai is almost attacked by a man in Dalton's room - who then disappears. They move house, but the events continue. Desperate, they call in a medium - who tells them that the cause of these occurrences isn't the house, but Dalton himself..
