Detective Donoghue Homer, played by Richard Jenkins, had been operating on the premise that Floyd’s death pointed squarely at Clark. But as he and Detective Jodie Plumb (portrayed by Joy Sunday) dig deeper, clues complicate that early conclusion.
New evidence and witness accounts increasingly draw the detectives into the strained relationship between Clark, Floyd and Floyd’s wife, Carol. What began as a seemingly simple homicide now looks tangled with long-running resentment and secrets tied to middle-age dissatisfaction.
The show’s official logline for Episode 6 warns that events escalate quickly — what was contained threatens to spiral out of control.
Key plot facts that matter
- Central trio: Clark (a disillusioned weatherman), Floyd (an ASL interpreter and stepfather) and Carol (Floyd’s wife) form the emotional core of the mystery.
- Crime scene detail: Floyd was discovered dead at a community pool several miles from his home, with a suggestive magazine found nearby — details that raise as many questions as answers.
- Investigative shift: Detectives uncover leads that open new lines of inquiry beyond the original suspect.
When the remaining episodes air
Episode 6 premieres on HBO and streams on HBO Max on Sunday, April 5, at 9 p.m. ET/PT. New episodes arrive weekly on Sundays.
The seven-episode limited run concludes with the series finale on Sunday, April 12.
