The three new stories were described in a press release on the Big Finish website:

"The set opens with Infamy of the Zarossby John Dorney, in which an alien invasion of Earth isn’t quite what it appears to be – Camille Coduri guest stars as Jackie Tyler.

In the second adventure, Sword of the Chevalierby Guy Adams, the Doctor and Rose arrive in Slough in 1791 and encounter Chevalier D’Eon, an enigmatic ex-spy who has lived his life as a woman. Together they must fend off alien slavers, who have come to Earth to abduct valuable humans.

Finally, in Cold Vengeanceby Matt Fitton, the TARDIS arrives on Coldstar, a vast frozen food asteroid in deep space. But there is something sinister defrosting in the network of storage units… the Doctor’s old enemies the Ice Warriors! Nicholas Briggsplays Ice Lord Hasskor and Warrior Slaan."
