Rick, a brilliant but reckless scientist, drags his anxious grandson Morty on dangerous interdimensional adventures. Their goal is often simple: acquire alien tech, escape perilous situations, or just have a wild time. This season, their escapades escalate, forcing them to confront the consequences of Rick's actions and Morty's growing moral compass.

The season's central conflict revolves around Rick's chaotic lifestyle and its impact on his family. Key turning points include Morty being forced to kill a powerful alien to prevent universal destruction, Rick's destructive relationship with a hive mind named Unity ending, and the family battling parasitic aliens that implant false memories. Rick nearly dies in a void, Morty kills a universe-threatening alien, and Unity abandons Rick.

The season concludes with a shocking betrayal at Birdperson's wedding. Birdperson is seemingly killed when his new wife, Tammy, reveals she's a Galactic Federation agent. Realizing Earth is compromised, Rick surrenders to the Federation, leaving his family behind on a Federation-controlled Earth.
