It starred Peter Hepworth and Kevin Wilson as two university students who begin to witness strange events while camping at Aireys Inlet in Victoria.
As the story develops, Steve observes other happenings, such as the lighthouse emitting a beam during the day which seems to match the timetable of passing cargo ships and the occurrence of the weaker event.
All the while, Steve is fostering a relationship with the mysterious old fisherman, Mirny, and police detectives in fedoras are seen poking about near the base of the lighthouse.
At the climax of the story, it turns out that Mirny is actually a member of an extraterrestrial race sent to Earth to procure deuterium oxide to use as fuel for their dying star which is Antares (or alpha Scorpii to use its Bayer designation).
The albatross, seen to disappear by Steve, flew into the operating transmat beam as deuterium oxide was being transferred from a passing cargo ship.
Another, equally difficult to procure children's series from the same production team, made around the same time, Andra, also exists based on the novel by Louise Lawrence.
