What would you do if a desperate phone call to your mother transformed a routine medical worry into a multi-generational death sentence?

In this episode, Jerry Halpern confronts his mother, Dorothy, with the terrifying results of his clinical sleep study. The confrontation unearths a devastating, carefully guarded family secret: the mysterious, rapid deaths of Jerry’s grandmother and Aunt Hazel weren't random tragedies. They were the opening acts of Fatal Familial Insomnia (FFI)—a rare, incurable genetic mutation that systematically dismantles the brain's ability to sleep.

Faced with a 50-50 genetic gamble that has finally come due, Jerry’s initial anger gives way to a profound new clarity. He isn't just a victim of his family's biology; he is the last line of defense for his two teenage daughters. Tune in as Jerry shifts from a man facing his own expiration date to a father launching a fierce, high-stakes mission to alter his family's genetic legacy before time runs out.
