Set four years after Nadia and Alan escaped mortality's time loop together, season two of Russian Doll will continue to explore existential thematics through an often humorous and sci-fi lens. Discovering a fate even worse than endless death, this season finds Nadia and Alan delving deeper into their pasts through an unexpected time portal located in one of Manhattan's most notorious locations. At first they experience this as an ever-expanding, era-spanning, intergenerational adventure but they soon discover this extraordinary event might be more than they bargained for and, together, must search for a way out.

Russian Doll sees lifelong New Yorker Nadia (Natasha Lyonne) fall into a time loop on the night of her 36th birthday. Every time she comes back to that night — in her friends' cosmically cool bathroom, she attempts to figure out what, exactly, is happening to her.
