Doctor Who (1963) Season 18 Episode 5 Meglos (1)

The Doctor and Romana arrive on the planet Tigella, known for its highly advanced civilization and legendary people called the Savants. However, they quickly discover that the planet is in the midst of a crisis caused by the theft of a powerful artifact called the Dodecahedron. The theft is attributed to a terrorist group known as the Gaztaks, but the Doctor is skeptical of this claim and suspects that something more sinister is afoot.

As the Doctor and Romana investigate the Dodecahedron, they encounter a strange and malevolent being called Meglos, who has taken on the form of a humanoid cactus. Meglos reveals that he is the true culprit behind the theft of the Dodecahedron, and that he plans to use its power to take over the universe and destroy his enemies.

The Doctor and Romana, aided by a group of Tigellan rebels, must race against time to stop Meglos and retrieve the Dodecahedron before it falls into the wrong hands. Along the way, they face numerous challenges and obstacles, including treacherous terrain, deadly booby traps, and fierce battles with Meglos' minions.

As the situation grows more dire, the Doctor must use all of his wit and ingenuity to come up with a plan to defeat Meglos and save the planet from destruction. Meanwhile, Romana must confront her own doubts and fears as she grapples with the enormity of the task before her.

In the end, the Doctor and Romana emerge victorious, but not without paying a high price. As they depart from Tigella, they are left to ponder the many mysteries and complexities of the universe, and to wonder what new adventures await them in their travels through time and space.
