The Fantastic Journey is an American science fiction television series that was originally aired on NBC from February 3 through June 17, 1977. The series concerns a family and their associates who charter a boat out into the Caribbean for a scientific expedition. After an encounter in the area of the Bermuda Triangle with an unnatural green cloud, the group find themselves shipwrecked on a mysterious uncharted island from which they are unable to escape.They encounter Varian (Jared Martin), initially disguised as an Arawak native, who is later revealed to be from the year 2230. A 23rd-century pacifist, musician and healer, Varian explains to the travelers that, like he and many before them, they have been caught in a space/time continuum where people from the past, present, future and from other worlds are trapped, co-existing on the island in a series of timezones. The only way home can be found in a place called "Evoland", which lies "far to the rising sun". (It was indicated in interviews of the time that Evoland was also the name of the island.) The only way to travel between timezones is via invisible gateways that instantaneously transport individuals or groups from one zone to another. In one episode "Beyond The Mountain" the group also encounters a second cloud, which has much the same effect, but which also splits up the group.

"Quatermass II" is a British science-fiction serial, originally broadcast by BBC Television in the autumn of 1955. Meteorites are falling over Northern England, one of which is observed by an Army radar unit. After a farmer finds one of the objects in a field, the soldiers become directly involved, and Captain Johnny Dillon decides to unofficially ask the father of his fiancée, Paula, to investigate. Paula's father is Professor Bernard Quatermass of the British Experimental Rocket Group — "the rocket man!", as one of Dillon's troops puts it. Quatermass and the Rocket Group, now including Paula and mathematical genius Dr. Leo Pugh, are recovering from the news that one of the twonuclear Quatermass II rockets has exploded during a ground test in Australia, killing hundreds of staff and ending their project to build permanent bases on the Moon.

The series continues the loose chronology of the Quatermass adventures, and begins with Professor Bernard Quatermass being forced out of his role at the British Experimental Rocket Group, with the organisation being passed into military control by the British Government. Quatermass and his new colleague Colonel Breen become involved in the discovery of a bizarre object at an archaeological dig in Knightsbridge, London. As the serial progresses, Quatermass and his associates find that the contents of the object have a horrific influence over many of those who come into contact with it. As this influence increases, affecting Quatermass himself, darker implications are revealed about the entire nature and origins of mankind.
