The Tomorrow People (1973) - 5x06 - The Heart of Sogguth, Part 2: Devil in Disguise- Followmy.tv

Jake tells John to stop Elizabeth telling anyone what happened, and gives him a knife. John jaunts back to the Lab and tries to kill Elizabeth, but his instinct not to kill breaks Jake's control. Mike and Jake go to the Hearts of Sogguth headquarters, but during a strange ceremony a voice warns Jake that Mike is different. Elizabeth finds an old book that predicts that Lord Sogguth will return when a million people hear the beat of his heart, and that he would destroy the Lords of the Heavens. Elizabeth thinks that the television broadcast will reach more than a million and the Lords of Heaven could be the Galactic Trig. The Hearts of Sogguth capture Mike, and something comes out of the sacred drum and takes control of him. When contacted telepathically by John and Elizabeth, Mike lies, saying that he is at home, and that the television programmed is the next day. John and Elizabeth jaunt to the Hearts of Sogguth headquarters to try to destroy the drum, but are discovered by Jake, who makes John attack Elizabeth. Jake tries to stab Elizabeth, but she jaunts back to the Lab. The next day Elizabeth jaunts to the television studio just before the broadcast; John tells Jake of her arrival, and persuaded Jake to let him stop her with a stun gun. Elizabeth is up on the gantry with a laser blaster, ready to destroy the drum, but is stopped by John before she can fire. Mike plays the drum in order to release Lord Sogguth, but Elizabeth manages to destroy the instrument. Sogguth is defeated, and, as he retreats back to the centre of the Earth, he takes Jake's soul with him, leaving behind just his skeleton.
