Captain Scarlet vs. the Mysterons. Plot While on patrol over the Sahara, Spectrum fighter pilot Symphony Angel (voiced by Janna Hill) is forced to eject after the tail of her aircraft mysteriously explodes. On the ground, she is overcome by heat stroke and passes out. In a transmission from Mars, the Mysterons (voiced by Donald Gray) warn Spectrum that they intend to destroy its airborne headquarters, Cloudbase. Cloudbase is placed on red alert and isolated from all external contact. Destiny Angel (voiced by Liz Morgan) has been launched to search for Symphony but is recalled by base commander Colonel White (voiced by Donald Gray) in view of the Mysteron threat. This action leads to a heated exchange between White and Captain Blue (voiced by Ed Bishop), who admits that he has romantic feelings for Symphony. However, White refuses to let Blue join the ground search. Night falls, and Captain Magenta (voiced by Gary Files) detects a large object on Cloudbase's radar. Rhapsody Angel (voiced by Liz Morgan) is launched to investigate and discovers a spinning Mysteron spacecraft that destroys her fighter in mid-air. When more craft arrive, Captain Scarlet (voiced by Francis Matthews) volunteers to challenge the Mysterons in Destiny's place. However, his fighter is damaged and he crash-lands on the Cloudbase flight deck, seriously injured. As the Mysterons open fire on Cloudbase itself, medical officer Dr Fawn is killed. Posing as his assistant, Mysteron agent Captain Black reports that Scarlet's powers of self-repair have failed him and that he is therefore permanently dead. The Mysteron attack intensifies, resulting in the deaths of everyone else on board except White, Blue and Lieutenant Green (voiced by Cy Grant). As the stricken Cloudbase loses altitude, another explosion kills Green and cripples Blue. Resolving to go down with his command, White stands to attention and salutes. As Cloudbase is heard crashing to Earth, Symphony wakes up in the desert facing Scarlet and Blue, who are part of the ground forces that have been sent to rescue her. In the final scene, it is revealed that Symphony merely dreamt the attack on Cloudbase in a nightmare brought on by the desert heat.
