Thriller is an American anthology television series that aired during the 1960–61 and 1961–62 seasons on NBC. The show featured host Boris Karloff introducing a mix of self-contained, macabre weird-horror and morbid, hitchockian crime stories, in some of which he also starred.

Sea of Souls follows para-psychologist Monaghan and his two sidekicks from a fictitious Scottish University that investigates paranormal activity.
