Let's Scare Jessica to Death.

Jessica goes to the Connecticut countryside for some rest following her release from an institution where she has just recovered from a nervous breakdown. She arrives with her husband and friend, but the three find little relaxation. Instead, they become entangled in a creepy tale of the supernatural which involves murder, an attempted drowning, a séance, disappearing bodies, vampires and constant torment for Jessica. Her marriage is strained, she hears voices, and she can't escape the mental turbulence which haunts her – for there really is something after Jessica.
