Deadhead (6x13)

:

A deadhead is a partially submerged log capable of impaling and sinking unsuspecting boats. Nick and Margaret spot such a log, but are unable to flag it. When the deadhead wrecks Ceece Neville's boat, and poor old Ceece is hospitalized, Margaret conducts her own vendetta on the killer log, with Relic providing unexpected complications.
