Sweltering under the summer heat of LA in July, Lacey Fitzpatrick begins planning an Alaskan cruise getaway for herself and her partner Sam, but her efforts are being constantly interrupted by annoying phone calls. Whoever it is, the person calls, says nothing, and hangs up. Then Sam starts getting the same kind of calls. The first possibility the duo considers is that some criminal they helped incarcerate is purposely irritating them or taking out a petty revenge, but after doing a bit of research, Lacey discovers that the caller - and the reason for the calls - is far more disturbing and complex. Now the question is, can the paranormal investigators really do anything to help?
