Flotsam (Thomas) is the daughter and helper of crusty old lighthouse keeper Joe Clark (Edward Ellis, in fine form). The reason why Clark lives 'out yonder' is because he's a fugitive from justice: years ago, he killed a man under complicated circumstances. Clark's official assistant is Amos Bart, but Flotsam does much of the work of maintaining the lighthouse.
