Ep 10. Timelash (1)

The Doctor and his companion Peri arrive on the planet Karfel, which is ruled by a tyrannical leader named The Borad. The planet is in a state of turmoil, as the inhabitants are plagued by a deadly sickness and forced to mine for a rare mineral called Ziton-7. The Doctor and Peri soon discover that The Borad is using the mineral to power a time tunnel, which he is attempting to use to travel back in time and change his own past.

As the Doctor and Peri explore the planet, they encounter the members of the underground resistance movement, who are attempting to overthrow The Borad. They also meet a scientist named Mykros, who has developed a device that can neutralize the radiation produced by the Ziton-7 mining operations. The Doctor and Peri agree to help Mykros and the resistance movement, and set about sabotaging The Borad's plans.

However, their efforts are complicated by the fact that The Borad has the ability to hypnotize people into doing his bidding. The Doctor himself falls victim to the hypnosis, and is forced to do The Borad's bidding until he is able to break free. Meanwhile, Peri finds herself caught in a dangerous game of cat and mouse with The Borad's chief henchman, a cyborg named Tekker.

As the Doctor and Peri struggle to outmaneuver The Borad and his minions, they begin to uncover the terrible truth about his past. They learn that he was once a respected scientist named Maylin Tekker, who was mutated by exposure to the Ziton-7 mineral. The Borad's obsession with changing his own past has driven him to commit terrible atrocities, and it is up to the Doctor and Peri to stop him before he can cause even more harm.

In addition to the main plot, the episode features several subplots that serve to flesh out the characters and their motivations. We learn more about the history of Karfel, including the role that Mykros played in the downfall of the previous ruler. We also get a glimpse into the Doctor's own past, as he reflects on the mistakes he has made in his travels through time and space.

Overall, "Timelash" is an exciting and suspenseful episode that will keep viewers on the edge of their seats. With its complex plot, well-developed characters, and high stakes action, it is a worthy addition to the Doctor Who canon. Fans of the series will not want to miss this thrilling adventure through time and space.
