The highly anticipated second season of Apple TV's science fiction series unveiled its first footage at San Diego Comic-Con, continuing the story of physicist Jason Dessen as he and his family attempt to forge a peaceful existence after the turbulent events of season one. The trailer suggests their hard-won tranquility in an alternate dimension quickly unravels when new, unspecified threats force them to flee once more.

Creator Blake Crouch and the principal cast gathered at the convention to discuss the emotional weight of their roles, which involve navigating parallel versions of themselves and exploring profound questions about identity, relationships, and the ripple effects of life-altering decisions. The series grounds its high-concept multiverse premise in intimate family dynamics and existential themes about the lives people might have lived.
