Zoya Lowe (Mary-Louise Parker) is a quantum physicist from Miami, FL. When she is diagnosed with a black hole growing in her chest and given a week to live, she finds herself stuck in a time loop. But what the doctors and her family don’t know is that she has already lived this week before. She’s lived it so many times, in fact, that she doesn’t even know how long it’s been. One day she meets Paula (Ayo Edebiri), a gifted student studying time at a lab in the local university. Together they decide to try and solve time travel so Zoya can go back— back into her past, back to when her whole future was still wide open in front of her—back so she can do it all over again, and finally be the person she always wanted to be.
