The Doctor and Jo take Mike Yates on his first trip in the TARDIS, but instead of the historical cricket match they were aiming for they end up on a futuristic space station in the middle of a diplomatic crisis that might escalate into galactic war.
The alien leader of the Chalnoth Hegemony is marrying the human Director of the Teklarn Incorporation, but there are forces that will stop at nothing to disrupt the ceremony. The Doctor is accused of murder while explosions occur across the station, and only Jo Grant, pretending to be a security consultant, can save the day.
But then, there’s the Eels to consider…
But not for long. Soon the Doctor's old enemies, the Sontarans, have landed, and are searching for the remnants of their previous research team. Before long they uncover evidence of strange occurrences on the planet. Of madness and death.
They are warriors bred for war, strong of spirit and unafraid of death. To fear the enemy is an act of betrayal. Nothing holds terror for the Sontarans.
