Hardened criminal Abslom Daak chooses a suicide mission as a Dalek Killer as an alternative to vapourisation. Daak survives transmission through space and arrives on the newly-colonised Dalek world of Mazam where the puppet ruler, Princess Taiyin, is about to be exterminated by her masters. Daak rescues her and together they make their escape from the palace and launch an attack on the Dalek base nearby. The attack is successful, but a stray Dalek survivor manages to kill Taiyin while Daak holds her in his arm. Half-crazed with grief, Daak swears to revenge himself on "every damned stinking Dalek in the galaxy!"
