Ep 4. Genesis of the Daleks, Ep. 4

The Doctor is tasked with a crucial mission — to travel back in time and stop the creation of the Daleks, the Doctor's most fearsome enemy. He and his companions land on the planet Skaro, home to the Daleks, during a war between the Kaleds and the Thals. The Kaleds are trying to develop a weapon that will end the war, and a scientist named Davros has created a machine that will do it.

The Doctor and his companions are captured by the Kaleds and taken to see Davros, who is wheelchair-bound and covered by a respirator. Davros is intrigued by the Doctor's knowledge of time travel and wants to use him to test his new weapon. Meanwhile, the Doctor is trying to figure out a way to stop the Daleks from ever being created.

As the Doctor and his companions make their way through the Kaled city, they encounter various mutants created by the war and are often caught in dangerous situations. They also must deal with internal conflicts among themselves and with the ethical implications of changing history.

The Doctor finally meets Davros, who shows him the Dalek incubation chamber, where the mutated Kaleds are turned into the metal-bodied Daleks. The Doctor tries to reason with Davros, pleading with him to abandon his weapon and not create the Daleks.

The final confrontation takes place as the Doctor is forced to make a decision that could change the course of history forever. As the Kaled's machine is activated, the Doctor must choose whether to let the Daleks be created and risk the destruction of the entire universe or to destroy the Kaled machine and end the war, effectively preventing the creation of the Daleks.

The episode concludes with the aftermath of the Doctor's decision. He and his companions reflect on the potential threat that the Daleks would have posed had they been left unchecked. The episode serves as a reminder of the Doctor's challenge to do what is right, even at the risk of making difficult choices and facing the consequences.

Overall, Genesis of the Daleks is a classic episode of Doctor Who, and fans of the series will love the exploration of the history of the Doctor's greatest foe. The episode is thrilling, engaging, and thought-provoking, making it a must-watch for sci-fi fans.
