Big Finish Doctor Who/Recap/S1/E04 Immortal Beloved/NEDA

The Doctor lands the TARDIS on a cliff. Once Lucie is done yelling at him for almost killing her that way, they notice two teenagers on the cliff (Prince Kalkin and Sararti) who are about to kill themselves for love. Lucie tries to talk some sense into the young Romeo and Juliet while the Doctor investigates.

The planet turns out to be a world colonized by humans, based entirely on Greek mythology. Three "Gods" are in charge: Zeus, his wife Hera, and their friend Ares.

Lucie, who quite fancies Kalkin, notices with some horror that he looks exactly like a younger version of Zeus. When Ares nearly dies, we find out why: Kalkin's best friend looks exactly like a younger version of Ares, and his body is used as Ares' new home. The planet is entirely populated by clone people of the three "Gods", who serve as younger bodies for their minds when the old ones expire. The "Gods" are simply astronauts from a crashed ship who got a nasty case of megalomania. They keep their "children" in the dark about technology, using mythology to mask what's really going on. And since Zeus is getting on a bit too, Kalkin is just within the right age bracket to provide his next body. Kalkin's love for Sararti is just a side effect of both of them being clones of a married couple.

Zeus wants to take Lucie on as his sex toy, and threatens to clone her and torture her offspring forever if she doesn't consent. She won't have it and tells him to sod off. The Doctor saunters in from the balcony to save her.

Since the clone machine is running out of "toner", the Doctor is roped in by Zeus to fix it. Ares, in the meantime, is killed. The Doctor goes along with Kalkin's new plan: they'll fake Zeus' transferral into Kalkin's body and kill the real Zeus before anyone notices. Sadly, they don't tell Sararti, and she has the exact same plan with Hera. In true Romeo & Juliet fashion, they each threaten suicide for a while over losing each other, but Lucie and the Doctor manage to tell them the truth just in time. Kalkin and Sararti decide to reign the planet together and pretend to be Zeus and Hera, without ever telling their subjects what happened and without ever using the transferral machine again. They realise that mortal life is much like delayed suicide, only a bit more ethical.

The Doctor tells Lucie that she's quite welcome in the TARDIS by now, and they flirt a bit, although she still thinks he's kind of a ponce.

The Headhunter is still searching for Lucie.
