Rick and Morty Episode 45: Rickdependence Spray

Morty becomes fixated on a horse-breeding machine at Beth’s workplace and starts using it for his own private purposes. A week later, Rick takes a barrel of horse semen from the hospital for an experiment meant to help him fight the underground cannibal horse people he has been battling, but the experiment goes disastrously wrong when Morty’s semen is mixed in.

The failed test creates giant, violent sperm that begin attacking people across the country. The President brings in Rick, Morty, and the Smith family to help deal with the crisis, and the episode turns into a large-scale military response against the sperm outbreak.

As the sperm threat grows, Rick and Morty are sent into the field with soldiers to track down the source. The mission goes badly, with most of the team being killed, and the chaos escalates further as the giant sperm continue to spread and cause destruction.

Meanwhile, the underground horse people become involved in the conflict, and Rick, Morty, and the others are forced into a complicated battle involving both the sperm monsters and their horse-world enemies. The episode ends with the crisis still spiraling out of control, capped by a bizarre final twist involving a giant fertilized egg launched into space.
