Ep 1. Day of the Daleks

The Classic Doctor Who season 9 episode 1 is titled "Day of the Daleks". The Doctor and Jo Grant travel back in time to the year 1973 to investigate reports of a guerrilla group known as the Ogrons. Upon arriving, they discover that Earth is under the control of a totalitarian government and a group of rebels is plotting to overthrow it. The Doctor and Jo wind up teaming up with the rebels, who have captured three time travelers from the future. These travelers have gone back in time to assassinate a political figure who, if left alive, will lead Earth into a catastrophic world war.

However, the Doctor soon discovers that the time travelers are Daleks, genetically modified creatures who have vowed to destroy all life on Earth. They have found a way to travel through time and have come back to ensure their own dominance in the future. To stop them, the Doctor and the rebels must find a way to stop the assassination while fending off attacks from the Daleks. The stakes are high, as failure would mean the end of humanity as we know it.

The Doctor, as always, is quick on his feet and devises a plan to defeat the Daleks. He enlists the help of the rebels, who fight bravely alongside him. Together, they manage to prevent the assassination and thwart the Daleks' plans. However, the Doctor knows that the Daleks are not easily defeated and that they will continue to plot against Earth in the future.

He knows that even the smallest event can have massive repercussions, and that it's up to him to prevent Earth from falling into chaos. With Jo by his side, the Doctor leaves 1973 and heads off to his next adventure, ready to face whatever challenges may come his way.
