Ep 3. Lemons

In Red Dwarf season 10 episode 3, titled "Lemons," the crew of the spaceship Red Dwarf find themselves in a bit of a pickle when they run out of lemons. The reason for their distress is that lemons are a crucial ingredient in the artificial intelligence system that controls the ship's engines. Without lemons, the system won't work and they'll be stranded in space forever.

Desperate for a solution, the crew sets a course for a planet where they hope to find a lemon tree. When they arrive, they discover that the planet is a desert wasteland with no signs of life. However, after some searching, they stumble upon a village where they are greeted by a group of people living in a medieval-like society.

The villagers, who are all played by the same actor, initially mistake the crew for demons and attack them. However, the crew soon makes it clear that they are not supernatural beings and that they are simply looking for lemons. The villagers, who have never heard of lemons before, are intrigued and the crew is invited to stay for the night.

During their time in the village, the crew learns that the society is made up of two feuding factions, the Cat Clerics and the Garbage Clerics. The Cat Clerics worship their feline overlords and believe that they hold the key to enlightenment, while the Garbage Clerics believe that the key to enlightenment lies in the study of garbage.

As the crew tries to navigate the strange customs and beliefs of the villagers, they also begin to uncover some of the secrets of the planet. They learn that the air is toxic, the sun never sets, and that the only source of water is guarded by a deadly monster called the Land Shark. Despite these challenges, the crew continues in their quest to find lemons.

As the episode progresses, tensions between the Cat Clerics and the Garbage Clerics escalate and the crew finds themselves caught in the middle of a battle. Meanwhile, Lister, one of the main characters, begins to form a bond with a young woman from the village, leading to some unexpected developments.

Ultimately, the crew is able to find the lemons they need and make their way back to the ship. However, they leave behind a society that is still very much divided and struggling to survive on a harsh and unforgiving planet.

Overall, "Lemons" is a classic Red Dwarf episode that combines science fiction, humor, and social commentary in a way that only this show can. With its memorable characters, clever writing, and imaginative world-building, it's a must-watch for fans of the series and newcomers alike.
