The Seventh Doctor and Mel pit themselves against the might of Sontar in our first September Main Range Release.

The Doctor Who Main Range brings you a new full-cast adventure every month, starring one of the original actors to play the Doctor on television! Featuring fantastic new creations or the best-loved monsters from the past of the series, these new stories are perfect for Doctor Who fans young and old.

Our 203rd release Doctor Who: Terror of the Sontarans continues our run of new stories perfect for listeners interested in checking out this popular range. Starring Sylvester McCoy as the Seventh Doctor and Bonnie Langford as Mel, his computer-programmer companion from 1980s Earth, this horrifying new story sees the pair face off against classic enemies the Sontarans.

Once it was a mining facility. Then later its corridors rang with screams generated by grotesque military experiments. However when the Doctor and Mel arrive on a hostile alien world after detecting a distress signal, the base they find themselves in is almost deserted.

But not for long. Soon the Doctor's old enemies, the Sontarans, have landed, and are searching for the remnants of their previous research team. Before long they uncover evidence of strange occurrences on the planet. Of madness and death.

They are warriors bred for war, strong of spirit and unafraid of death. To fear the enemy is an act of betrayal. Nothing holds terror for the Sontarans.

Until now...

Starring Sylvester McCoy and Bonnie Langford and co-written by John Dorney and Dan Starkey (better known as TV's Strax the Sontaran!), Doctor Who: Terror of the Sontarans gives listeners a perfect taste of the world of Big Finish – with plenty of surprises for long-term fans!
