Sea of Souls

Dr. Douglas Monaghan and his his two assistants investigate the case of Carol Fleming, a personal friend of Monaghan's, who sees her double, Helen Reid, at a local museum. The women chat over coffee and learn that they share the same taste in art and are both married to men named Gordon. When they realize that they are the same age and have the same birth date, they realize they must be twins. Monaghan is interested in Carol's dreams where she sees herself and twin girls watching a doll's house burning. He invites Carol and Helen to come to the lab to see if they have a telepathic connection as well and they score an almost unbelievable 100% on the test. After an auto accident in which her husband is killed, Helen moves in with Carol temporarily but but Carol begins to worry when her husband shoes an interest in her identical twin. Carol has her own secrets however and as their relationship deteriorates, so does their telepathic ability.

Helen can't understand why Carol would put her ideal home situation in jeopardy by having an affair with Mike and even impersonates her sister to break off the relationship. She's also studying the intricate details of Carol's childhood. When her boyfriend Mike is murdered, Carol has feelings of guilt and Monaghan isn't sure if she might be unstable. As Monaghan's assistants look into Helen's background and childhood, they begin to realize that she is the one who may be seriously disturbed. It becomes obvious that one is setting the other up for Mike's murder and it's left to Monaghan to sort out who is who and who has done what to whom.

Monaghan and his assistants investigate paranormal phenomena, specifically the transference of souls from the dead to the living or, more simply, reincarnation. After an unsuccessful trip to Lebanon where a young boy apparently had detailed memories of another life, they're faced with the case of 6-year-old Joe Quinn who starts to have memories of another life belonging to someone named George: a home by a lake; that his "other mummy" had red hair; and of a drowning. Is he however remembering a past life?

Findley Morrison seeks Monaghan's assistance when strange things happen in his house. All family members, including his wife Carol, son Dominic and daughters Claire and Martha have heard noises, experienced doors opening or closing and perhaps even seen images of someone moving about, though never clearly. Douglas and his assistant Justine McManus spend some time in the house and they too begin to experience some of these strange occurrences. They are also beginning to see the numbers 2976 being repeated.

Douglas and Justine continue their investigation, even though they were asked to leave the Morrisons house. From the family's reaction, Justine suspects that the strange occurrences may be linked to a Bolivian woman named Lygia who worked as a nanny for the Morrisons some years before, She follows up with Findlay Morrison who says that Lygia returned to Bolivia and has successfully completed law school since. It turns out the Morrisons paid her tuition as well. Douglas still thinks that Claire is the focus of any paranormal activity and decides to test her. As the volume of information continues to grow, Justine finds a vital clue. Douglas was correct in his thinking, only it's someone other than Claire with whom Lygia has made a psychic connection.

Daniel Blakemore seeks out Dr. Douglas Monaghan but has a strange way of doing it - he steps out in front of Monaghan's moving car. He's not hurt seriously however and soon, Monaghan and his team are fascinated by the close mouthed man who clearly appears to have precognitive abilities, that is, the ability to predict future events. Daniel mentions that he was in the military and when he disappears - Douglas suggested he might be suicidal - he and his assistant Craig Stevenson pay a cal on his Regiment. The Chief Medical Officer, Lt. Col. Petra Summers, tells him that Daniel is AWOL and if suffering from trauma as a result of his military service in Bosnia. She would like him to return to continue his treatment but Douglas wonders exactly what may be going on.

A young couple, Angus and Caroline Jenson, hold a seance to contact their recently-deceased son. Something goes wrong and Angus is thrown against the wall by a powerful spirit. When he starts to experience blackouts and has a vision of a car plunging into the water, he visits the Department of Parapsychology at Clyde for counsel. As he becomes increasingly violent, the team races to determine who or what has possessed him.

Believing that a scarf has set off a premonition of a local woman's death, Justine tries to locate her to prevent the terrifying vision from coming true.

Justine agrees to help one of the students in her tutor group with a research project involving monitoring the girl's boyfriend's sleep patterns. The boyfriend, Stuart, has been suffering from lack of sleep due to terrible nightmares. Stuart's dreams seem to be able to manifest in the physical world, and Justine along with Stuart, his girlfriend Chloe and another friend, begin to experience some unsettling manifestations - including a room full of moths. Dr. Monaghan arrives to help, but the group find themselves trapped in the university. Unable to wake Stuart, they must try to work out what is causing the manifestations before it is too late.

When a young couple, Karen and Ian O'Rourke, move into an old home they discover unique symbols painted on the walls. When they post the image on the Internet, Dr. Douglas Monaghan believes they have found the Tree of Life, a symbol of the Order of the Golden Dawn, a 19th century spiritualist group. At the end of the 19th century Robert Dunbar, a spiritualist, occupied the home and he may have decoded a cipher manuscript that was central to the Order. As Monaghan researches the history of the house he learns that it has a macabre history including the previous owner who was found dead at the bottom of the stairs and Dunbar himself who killed his wife and was hung for it. As Karen begins to see spirits from the past, she desperately wants to leave the house and move on.

As Professor Monaghan continues his research into the house, he finds that there may have been other beliefs at work there and suggests to the O'Rourke's that they leave the house. When they find Rebecca Muir's diary, Monaghan starts to fill the gaps in the history of the house and the Dunbars. What he learns however is that the O'Rourke's may not have acquired the house by chance and that the spirits there have designs on the O'Rourke's themselves.
