Hook, Line & Sinker is a hilarious comedy starring the Bert Wheeler and Robert Woolsey comedy duo. Wheeler and Woolsey are dodgy insurance salesmen who bump into Mary (Dorothy Lee) who has just inherited a run-down hotel and they invite themselves to help her out.
Not only is the hotel in need of some renovation but two rival gangs of criminals (one gang including Natalie Moorhead as a fake duchess) are trying to break into the hotel safe. Wheeler and Woolsey also fall in love with Mary and her mother (Jobyna Howland).
What follows is a complicated farce packed full of corny (but funny) wisecracks. Hotel situations have often been a rich source for humour and this film is no exception.
