The year is 1982, and a beautiful young woman, dressed in Edwardian clothing, is found floating unconscious in the North Atlantic with a 1912 boarding pass to the RMS Titanic.
Over in England, Callum Toughill, an insurance investigator, is assigned the case of a missing brooch that was stolen during a horrific, unsolved murder in 1909 Glasgow. He is chosen because it was his own grandfather who had botched the original investigation. Despite the painful family memory and likelihood that all evidence will be long gone, Callum dives in. As he begins to uncover the tangled truth that the missing brooch may have ended up on the ill-fated RMS Titanic, someone is one step ahead, trying to stop him.
Miraculously the mysterious young woman, nicknamed 'Myra' because of the inscription on her locket, survives and awakes in a Manhattan hospital with no memory of who she is. Myra’s vague recollections are from the gilded age of 1912 and she is lost in the alien, harsh world of 1982. A respected and wealthy Titanic survivor named Edward Hoffman assists in exposing her as a fake, but the plan backfires and stirs up more details in Myra's memory which include the fact that Edward may be her son.
Is it a bizarre case of time-travel or an elaborate hoax?
