Beyond living in his disapproving mother-in-law's house while he establishes his accounting career, Bill Denny is happily married to Kate Denny; they're about to celebrate their second wedding anniversary. Bill thinks he's 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. However Kate believes her anniversary present is the terrier who followed Bill home, and she names him Archie. Bill and Kate don't know that the terrier escaped from its owners, a bunch of smugglers who trained it to be the contact for the switch between the smuggled goods and the money. Bill and Archie don't get along, so Bill does whatever he can to get rid of the dog. Meanwhile, the people buying the smuggled goods believe that the smugglers have swindled them since the terrier has not made contact, so when ads appear in the lost-and-found section about a missing Welsh terrier, Bill unwittingly gets caught in the middle as he tries to return Archie to her rightful people, and Kate can't understand why Archie is always trying to go off on their walks (when he's just doing what he was trained to do, trying to make contact for the drop). Add a harried police detective investigating a series a murders in which Bill seems to be involved, and chaos ensues.
