Dark Space 8 - an advanced monitoring station floating serenely among the stars. Its crew - a dedicated and highly skilled group of professionals calmly going about their vital work. Its mission - to boldly host the Intergalactic Song Contest. With representatives from myriad worlds competing, the eyes of the universe are on the station. But dark deeds are afoot aboard Dark Space 8...and people are starting to die.
When the evil Skelloids launch an attack upon the 17 worlds of the Generios system, its peace-loving inhabitants face total destruction. So it's fortunate that the famous traveller in time and space known only as the Doctor is in the area - and doubly lucky that with the help of his pretty young assistant, Sally-Anne, he manages to defeat the deadly creatures and save the day. But now it looks as though the Doctor's luck has run out.
