Doctor Who (2005) Season 6 Episode 17 The Invasion: Episode 7

The Doctor returns, along with his companions Amy and Rory, to present-day Earth as they investigate a series of strange power outages around the globe. As they explore the source of the outages, they discover that an alien race known as the Cybermen have invaded Earth and are using the planet's energy to power their invasion fleet.

The Doctor and his friends team up with UNIT, a military organization dedicated to defending the Earth from alien threats, to stop the Cybermen from taking over the planet. Along the way, they meet a woman named Dr. Trisha Evangelista, who has been kidnapped by the Cybermen and turned into a Cyber-Planner - a human who has had her brain merged with a Cyberman's technology.

With the help of Dr. Evangelista, the Doctor begins to formulate a plan to stop the Cybermen's invasion. But as they work to shut down the power source that the Cybermen are using, they discover that the situation is far more dire than they had initially thought. The Cybermen are using a device called the Pandorica, which contains a powerful and ancient being known as the Time Vortex.

If the Cybermen are able to fully activate the Pandorica, they will be able to use the power of the Time Vortex to conquer the universe itself. The Doctor realizes that he must stop the Cybermen at all costs and, with the help of his friends and the UNIT soldiers, engages in a battle to prevent the Pandorica from being fully activated.

As the battle rages on, the Doctor finds himself confronting some of his deadliest enemies, including Daleks and the mysterious Silence, who have been manipulating events in the background. With the fate of the universe hanging in the balance, the Doctor must use all of his cunning and intellect to outwit the Cybermen and save the day.

But even as he triumphs over the Cybermen, he realizes that there is still much he has yet to discover about his own past and the mystery surrounding his true identity. The Invasion: Episode 7 is a thrilling adventure that will keep Doctor Who fans on the edge of their seats as they follow the Doctor's journey to save the world from a deadly alien threat.
