Two Jon Pertwee adventures involving one of the Doctor’s greatest nemeses. Two six-part stories are included: Frontier in Space (which marked Roger Delgado\'s final appearance in the role of The Master) and Planet of the Daleks, which boasts a colour-restored version of the previously-lost third episode. In \'Frontier in Space\', the Doctor and Jo (Katy Manning) are caught up in the tensions between the Earth and Draconian Empires in a 26th-century interplanetary war. In \'Planet of the Daleks\', the Doctor lands the Tardis on the dangerous planet Spiridon, home to a terrifying army of Daleks.
