Andy Clyde wants Franklin Pangborn to keep his mind on the canned lobster business instead of love. He wouldn't even have a woman in the house, until Dorothy Granger shows up, feigning amnesia to get in and vamp the old boy.
The version I looked at ran half the length it was originally set at, so obviously things have been left out. I suspect this was a good thing; in this period, Mack Sennett's movies were mostly directed by Burl Cranford 'Babe' Stafford, and tended to run slow and a little dull for my taste. If most of the stuff cut out was the exposition, then it's clearly a good thing. Of course, the alternative interpretation is that this was the first half of the movie as re-issued in two parts.
