Ep 19. Warriors' Gate: Part 3

The Doctor and Romana have been trapped in another universe, while Adric and K9 have been stranded aboard the TARDIS. As the two groups try to find their way back to each other, they become embroiled in a dangerous game of political and personal intrigue between the Tharils, a race of once-proud warrior slaves, and their cruel masters, the Gundans.

The Doctor and Romana have found themselves in the midst of the Tharil's hidden stronghold, where they learn more about the history of the weapon that destroyed the Tharil's home world and enslaved their people: the Gateway. As the Tharils debated whether to use the Gateway to escape their captivity, the Doctor and Romana try to keep them from making a terrible mistake that could have disastrous consequences.

Meanwhile, Adric and K9 are still aboard the TARDIS, searching for a way to reunite with their friends. But they quickly find themselves in danger when a group of Gundans board the ship and threaten to destroy them if they do not surrender the Time Lord's technology.

As the two groups navigate the treacherous political landscape, they begin to realize that their fates are intertwined in unexpected ways. The Doctor and Romana must rely on their wits and their knowledge of science and history to outmaneuver the manipulative Gundans, while Adric and K9 find themselves caught up in a revolution led by the Tharils.

With time running out and the fate of entire universes at stake, the Doctor and his companions must work together to defeat their enemies, protect the innocent, and find a way back home. But will their efforts be enough to overcome the powerful forces aligned against them, or will they be lost forever in the eternal void of the Gateway?
