Château Laroche is a beautiful hotel perfect for any weekend get-away. However, the owners, François and Mimi Laroche, are horrified to discover the enormity of their cockroach problem as they prepare for a big weekend of visitors. In fact, the cockroaches have appeared just in time to make a good impression on a famed travel writer. They've also learned the health inspector is making a surprise visit—disguised as a typical guest! Could the inspector be one of the young honeymooners? The wealthy widow or her hypnotist? The British bicyclist? The manager of a bratty child star? François launches an all-out war on the creepy-crawly creatures as the disgruntled staff members struggle to hide the pesky problem from the hotel guests. Even with the help of two zealous exterminators, Roskel T. Goomey and his little sister, the roaches quickly and hysterically adapt to the chemical assault and begin to grow bigger, while the supposed health inspector hallucinates after mistakenly using the toxic bug powder on his spaghetti, thinking it was Parmesan cheese! Will the guests make it out alive? Will François and Mimi lose Château Laroche?
