While conducting a wellness check on the agoraphobic recluse who controls the town power grid and has stopped taking his meds, Martin's brusque bedside manner ultimately causes a massive town black out.

When Port Wenn puts on their annual "Blood Factory," celebrating the gory horror novel set there, Martin must contain his secret debilitating blood phobia when Louisa gets seriously ill and needs his help.
