Vila Cally Gan Jenna in teleport room S-L-D

Vila prepares to teleport down to Cetero.

Teleporting down to the planet Centero, Blake and Vila manage to infiltrate the Federation's communications centre and take the technicians on duty prisoner. Avon, Cally and Gan join them and begin planting explosives throughout the centre; Cally and Gan take the technicians and troopers to another room to guard them. Avon attempts to remove the cypher machine from the control room, which the Federation will hopefully believe was destroyed in the explosion, but Gan is needed to rip it free. Left alone, Cally is overpowered by the prisoners and loses her teleport bracelet. She is left behind when the rest of the team teleport back to the Liberator. With the explosives detonating and the Federation launching interceptors after them, the crew are forced to give her up for dead.

Federation Space Command S-L-D

Space Command.

Federation Supreme Commander Servalan is visited by Senator Bercol and Secretary Rontane, the representative of the President, to enquire about Blake remaining at large and a threat to the Federation. Servalan replies that she is appointing an officer to the sole task of eliminating Blake: Space Commander Travis. Travis is a controversial figure in the Federation, who has only just returned to duty after ordering a massacre of a civilian uprising on the planet Auros.

The Liberator crew use the cypher machine to listen in on Federation transmissions and hear a mention of Travis. Blake knows Travis of old since he was responsible for Blake's original arrest: Travis and his men hid at the rebels' meeting place three days before the meeting took place and Travis ordered them to open fire when Blake surrendered. In the confusion, Blake shot Travis and believed he'd killed him. In reality, Travis' life was saved by a field medic but has been left with a damaged face and an articial arm.

Travis S-L-D

Travis is briefed on Blake.

Travis travels to Centero to investigate the crime scene and instructs the head technician, Prell, to make a thorough examination of the wrecked control room. Cally is found alive but unconscious in the wreckage and is taken back to the command station for interrogation. Prell notices than a panel that should not have been exposed was damaged in the explosion and realises the cypher machine has been stolen. Servalan wants to change the codes but Travis proposes sending out a message to lure Blake into a trap.


Blake surprises Travis.

Jenna picks up the message stating Cally is alive and is being taken back to Centero as a prisoner. Blake resolves to rescue her. Travis speaks to Base Commander Escon who reports that they are prepared to detect the use of a teleport and also that the Liberator did a fly past of the planet before Travis was arrived but is now out of range. However, when Travis goes to check on Cally, he is overpowered by Blake, who followed Travis' example and arrived on the planet before him and has already freed Cally. The Liberator teleports them both aboard and Travis vows to continue his pursuit.
