Doctor Who (2005) Season 10 Episode 19 Planet of the Daleks: Episode 5

The Doctor and his companion Jo Grant find themselves stranded on the planet Spiridon in the midst of a war between the Daleks and a group of Thals. They narrowly escape capture by the Daleks and stumble upon a hidden Thal base. There they uncover a plot by the Daleks to release a dangerous bacteria, deadly to all forms of life except for the Daleks themselves, into the universe.

As the Doctor and Jo work with the Thals to stop the Daleks, they encounter various obstacles and challenges. They navigate treacherous jungles and evade deadly creatures, all while racing against the clock to prevent the release of the bacteria.

Meanwhile, the Daleks have their own problems to contend with. As their numbers dwindle and their power source is depleted, they must resort to desperate measures to stay alive and continue their mission.

The Doctor and his allies eventually uncover the Daleks' plan to launch a spaceship carrying the bacteria into space, and mount a last-ditch effort to stop them. But even as they succeed in preventing the release of the deadly bacteria, they face one final showdown against the remaining Daleks.

In the end, the Doctor and Jo are victorious, but not without paying a heavy price. They leave the planet Spiridon forever changed, having faced danger and adversity at every turn and emerging as heroes in the face of impossible odds.
