When Port Wenn goes dark, who will the townspeople blame? As usual, the grumpy new doc Martin Best (Josh Charles) takes the brunt, after he performs a wellness check on an agoraphobe who oversees the local power grid but has stopped taking his meds. The ensuing blackout provides romantic cover for Louisa (Abigail Spencer) and Mark (Josh Segarra), while Doc Martin has an unnerving encounter with a boy who reminds him of himself.

Followed by a new episode of Doc (9/8c), where things are a lot more serious when Dr. Amy Larsen (Molly Parker) and her ex, Michael (Omar Metwally), are summoned to join their troubled daughter Katie (Charlotte Fountain-Jardim) for a therapy session after her recent panic attack. Back at the hospital, Amy helps her current flame, Jake (Jon-Michael Ecker), treat a mother-to-be who was injured during a robbery, while TJ (Patrick Walker) and Sonja (Anya Banerjee) help nurse Julie (Claire Armstrong) deal with a mystery illness.

Oscar winner Will Smith started his 100-day global adventure at the South Pole. In the docuseries’ finale, he finally makes it to the North Pole.

Hurdles include a snowstorm (what did they expect?) and mechanical issues, and as Smith teases, “We stayed under a little too long.”
