When scientist Jim Marshal disappears from work, leaving only a mysterious letter saying that his research assistant Deidre will know what has happened, Deidre and Jim’s distraught wife Beryl try to find where he has gone.

Their search flings them across space and into the power of sinister aliens – a beam that can transport them to another planet. These powerful aliens have collected people from Earth, and are studying them, putting them through strange experiments. Is it just scientific curiosity, or are there darker designs behind it? And, stranded on an alien planet, is there anything Deidre, Beryl and Jim can do?
