TEXT: 5:15pm - 5:40pm [SCENE_BREAK] 1: INT. COURTROOM RECEPTION (BARBARA is holding the receiver. SUSAN'S voice can be heard at the other end.) SUSAN: (OOV.) Aah... I want to talk to Barbara Wright. BARBARA: Susan? SUSAN: (OOV.) Barbara, they made me call you. BARBARA: Who, Susan? Who? SUSAN: (OOV: Terrified.) Barbara, listen there was... ah! (The sound cuts out.) BARBARA: Susan? Susan? Are you there, Susan? SUSAN: (OOV: Quietly.) They're... they're going to kill me. (A look of alarm crosses BARBARA'S face.) BARBARA: Su...? (The line is cut off.) SABETHA: We must tell Tarron. BARBARA: (Firmly.) No. SABETHA: Well what else can we do? We've got to find her. BARBARA: Yes, of course we have, but... ALTOS: You're thinking of the Doctor?

Who'd suspect the Chief Investigator? He was next to Aydan in court when he was killed. SABETHA: What do we do, Barbara? BARBARA: We find Susan ourselves. ALTOS: And remember, whoever is behind this kidnapping is either in league with the murderer or is the murderer. BARBARA: Trouble is, where to begin? Best thing we can do is to go over everything that's happened to us since we landed in Millennius. There's a link somewhere and it's probably the one and only way to save Ian. [SCENE_BREAK] 2: INT. CELL (IAN is standing in a cell, presided over by a GUARD.) IAN: How much longer? GUARD: Executi
SUMMARY:
The TARDIS arrives on the planet Marinus on an island of glass surrounded by a sea of acid. The travellers are forced by the elderly Arbitan to retrieve four of the five operating keys to a machine called the Conscience of Marinus, of which he is the keeper. These have been hidden in different locations around the planet to prevent them falling into the hands of the evil Yartek and his Voord warriors, who plan to seize the machine and use its originally benevolent mind-influencing power for their own sinister purposes.
