While touring abroad in Europe, beautiful American skydiver Fathom Harvill gets wrapped up in international intrigue when Scottish spy Douglas Campbell recruits her to help him on a secret mission. Before long, Fathom realizes that no one around her, including the mysterious Peter Merriweather, can easily be trusted, leading to various adventures that involve bull fighting, beaches and, of course, romance.
Unfortunately the movie Fathom is not yet available on HBO Max.
