The Tomorrow People

Secret Weapon, Part 3: Whose Side Are You On, Professor? (3x3)

:

Elizabeth jaunts to Prof. Cawston's office, watched by Col. Masters and Tricia. She gives the professor a ring with a homing device in it, but he is kidnapped by Masters before he can use it. When John and Elizabeth investigate, they narrowly escape an explosion, as the colonel has set the ring to self-destruct. Cawston is hypnotised and interrogated by the colonel, and reveals information about the Tomorrow People. Col. Masters wakes Tyso and tells him to contact the Tomorrow People telepathically. John and Elizabeth arrive at Col. Master's office in the Experimental Weapons Establishment, and stun him and Tricia. Cawston shows them where the antidote for the Synaptrol is, but Tricia comes round and hits them all with the drug. John manages to jaunt to the Lab, but then collapses. Col. Masters revives Elizabeth, and tells her to help them or Stephen and Tyso will die.
