Behave Yourself is an American comedy starring Farley Granger and Shelley Winters. While living in his disapproving mother-in-law's house, mild mannered, young, CPA, Bill (Farley Granger) establishes his accounting career. Bill is happily married to Kate (Shelley Winters), the two of them are celebrating their second wedding anniversary. Bill thinks he has come home without a present for Kate since a stray Welsh terrier caused a ruckus in the store where he was going to buy the present for Kate. However, Kate believes her anniversary gift is the terrier who followed Bill home, and who Kate eventually names Archie. What neither Bill or Kate is aware of is that the terrier escaped from it's owners, a bunch of smugglers who trained the terrier to be the contact for the switch between the smuggled goods and the money. Bill does whatever he can to get rid of the terrier as he and Archie don't get along. Meanwhile, the people buying the smuggled goods believe the smugglers have swindled them since the terrier has not made contact. When ads appear in the lost and found section about a missing Welsh terrier, Bill, in trying to return Archie to his rightful owners, unwillingly gets caught in the middle. Kate can't quite understand why Archie is always trying to go off on their walks, not knowing that Archie was trained to do this in trying to make contact for the drop. Add to this a harried police detective investigating a series of murders in which Bill seems to be involved, and chaos ensures. (80 minutes - 1951 - Black & White - 4:3).
