Ep 4. World's End (1)

The Doctor and his companion, Rose, find themselves on a desolate planet known as "The End of the World." They have arrived on a special invitation to witness the final moments of the universe and the last of its inhabitants. The planet itself is a feat of engineering, a massive space station made up of a variety of ecosystems, each with its own distinct life forms.

As the Doctor and Rose move through the station, they encounter a variety of colorful characters including the Cat-People of New Earth, the trees of Cheem, and the aquatic Fish People. However, something sinister seems to be lurking beneath the surface of the station, and the Doctor senses that not all is as it seems.

As the clock ticks down to the end of the universe, things begin to get increasingly dangerous. The station's security systems start to malfunction, cutting off access to crucial areas and trapping the Doctor and his companion in deadly traps. Meanwhile, a group of mysterious hooded figures seems to be behind the chaos, and it falls to the Doctor to figure out their motives before it's too late.

As the clock strikes midnight and the final end of the universe begins, the Doctor and his companions must fight for their lives against an unknown threat. Tensions are high, and the stakes have never been higher. Will they be able to save themselves, or will the world end with a whimper instead of a bang? Only time will tell.
