Rob and Laura Petrie are enjoying a quiet evening at home watching TV when they receive a phone call from their friend and neighbor, Millie Helper. Millie, who works at the jewelry store, explains that she needs their help with something urgent. She reveals that a valuable diamond necklace, known as Empress Carlotta's Necklace, has been stolen from the store and she believes the thief may have hidden it in their house during a party they hosted the night before.

Rob and Laura reluctantly agree to let Millie and her boyfriend, Jerry, search their home for the missing necklace. However, things quickly go awry as the couple becomes suspicious of everyone, including their own friends.

The tension mounts as Millie and Jerry tear apart the house looking for the necklace, and Rob and Laura gradually become more and more annoyed with their uninvited guests. Meanwhile, Rob's boss, Alan Brady, stops by unexpectedly and gets drawn into the chaos, complicating matters even further.

As the search drags on, Rob and Laura begin to suspect that Millie and Jerry are actually the thieves and have fabricated the story about the jewelry store robbery. With the help of Alan, they set a trap to catch the culprits in the act, but things don't go exactly as planned – resulting in a hilarious and unexpected conclusion.
