Insidious (Collection)

A series of American horror films where the plots are depicted as cases of demonologists. The first two films focus on a couple who, after their son mysteriously enters a comatose state and becomes a vessel for ghosts in the astral plane, are constantly haunted by demons from a hellish realm known as the Further, until they take from the family what they want most: life. The third film, a prequel, focuses on the same psychic who helped the family, this time coming to the aid of a young girl who calls upon the dead.
