The Doctor heads back to Earth with Mel and Hebe in tow, little dreaming what lies ahead. Accompanied by their new friend, Professor Patricia McBride, alien threats abound, dangers lurk, and the cost of meddling with time is more than anyone is prepared to pay.

When Patricia is invited to a secretive Swedish clinic by an old colleague, she tips off the Doctor, Mel and Hebe, who go undercover to investigate. Charismatic geneticist Killian Holm offers to restore youth to his wealthy patients, but the truth of his work is far more radical - and far more dangerous!

2.3 Chronomancer by Robert Valentine (2 parts)
The Doctor, Mel and Hebe take Patricia to see 26th century Sheffield, but their trip is cut unexpectedly short. Caught in the crossfire between time-criminal, Khavûl, and dashing ‘chronomancer’, Tannus Vallon, the TARDIS crash-lands back in the present.

With a dimensionally transcendental artefact lost somewhere in the city, the Doctor and his friends must find it before Khavûl can... but with resentments and prejudices finally unmasked, is an even bigger threat about to engulf the world?
