Starting with this installment, the BBC series experienced a rebirth of sorts with a new theme, a new logo and a fresh title sequence. Needing a respite, the doctor (Tom Baker) and his friend Romana (Lalla Ward) journey to an improbable vacation resort on the postapocalyptic planet of Argolis, but trouble soon rears its head thanks to a lunatic who's bent on resurrecting the past. Extras include a documentary about the show's extensive changes.
