Immortal Beloved is an audio drama based on the long-running British science fiction television series Doctor Who.

Two star-crossed lovers, Kalkin and Sararti, have been preparing to kill themselves nearby, but the Doctor and Lucie prevent this, and soon anachronistic helicopters surround them all.

The Doctor confronts Zeus, the autocratic ruler of this strange society where guns are labelled as magic wands and the hi-tech mind-transfer device is an 'incarnation chamber'.

The ruling class, the remains of the original crew – the 'gods' – use their machine, which the Doctor insists has long been outlawed as an abomination – to transfer their minds periodically into their clones, giving them practical immortality.

He reveals himself to be a madman, and demands that the Doctor use the TARDIS to fetch parts to repair the immortality machine, as it has become worn out and they are now without space-travel capabilities.
