Today is Jimmy's last day alive. His Alzheimer's is worsening, so he's decided to die like he has lived - with intention, humor, and zest. In his last day on Earth, Jimmy will show an obituary writer, his death doula, his estranged brother, his caretaker, a surreal being, and the guests at his fabulous FUN-eral, that perhaps the art of living is the art of dying.

Three mysterious figures emerge from the Mojave Desert and make their way to Los Angeles, leaving a trail of bodies in their path.
