On planets where a Krynoid seed lands, all animal life is doomed. This carnivorous plant first appeared in the 1976 Doctor Who TV story The Seeds of Doom, in which the Doctor saved Earth from a Krynoid infestation. But not all worlds are so lucky. 

Planet Krynoid: Nightfall, the first box set in a new audio drama series, is a three-hour disaster adventure, which begins with a seed pod infecting the seemingly utopian planet of Sunlight. Before long, life on Sunlight has become a nightmare. 

Leading the fight back is Governor Robert Hodan – played by British horror icon Reece Shearsmith (Inside No. 9, Psychoville, The League of Gentlemen), here making his Big Finish debut. 

Shearsmith said: “I know a lot of actors on Big Finish’s roster – David Warner was a great friend, and he used to love doing them and would tell me about them: ‘Why haven't you done one?’ So I was thrilled to be asked to be in this. It’s a really huge drama, it feels a proper disaster movie of the 1970s, like The Poseidon Adventure – things just get worse and worse.” 

The large cast of characters also includes xenobiologist Bryn Forrester (Melody Chikakane Brown) and the impoverished Hart family (Sarah Whitehouse, Ian Conningham, and Nye Occomore). 

And, the second episode of the box set includes a guest appearance from the Eighth Doctor (Paul McGann). But with the Krynoid’s tendrils extending across the planet, no one is safe – not even the Doctor. 

The Worlds of Doctor Who – Planet Krynoid: Nightfall is now available to pre-order for just £24.99 (collector’s edition CD box set + download) or £19.99 (download only), exclusively here. 

For a hundred years, Sunlight has been a beacon of hope shining across a troubled galaxy, an artificial paradise on a frozen world offering safe haven for the super-rich, and employment for even the poorest of labourers. At least, that’s what the adverts say. 

Unfortunately for Governor Robert Hodan, one of his engineers has just discovered a pair of strange-looking pods lodged in a satellite. So Sunlight, that glittering verdant oasis, will never be the same again. 

Because, as the Doctor knows only too well, on planets where the Krynoid gets established, the vegetation eats the animals… 

The three episodes in the box set are: 

Sunlight by Jonathan Morris 

Sunset by Jonathan S Powell 

Darkness by Chris Chapman

Producer Jonathan S Powell said: “Planet Krynoid is Doctor Who’s answer to The Last of Us and The Walking Dead, a heart-stopping vision of society's collapse under the weight of one of television's most terrifying creations: the Krynoid. 

“The Krynoids themselves are terrifying because they do that great sci-fi thing of inverting the ordinary and making you petrified of pot plants. More than that though, they're a sentient infection utterly antithetical to our existence, for which we are woefully unprepared, which makes them the perfect monster to explore today, half a century on from their debut. 

“I adore The Seeds of Doom – not just for its B-movie brilliance, but for the creeping feeling it evokes that this time, for the first time, the Doctor really might lose. That's what we've tried to convey in this set, that the gloves are off and nobody is safe.”
