2 contestants embark on a tour of 3 flats. In each of the flats they encounter a different couple of tenants. One of the couples they will encounter will pose under a fake identity. Will the contestants succeed in revealing the fake couple? If they succeed, they will win $10,000. If our pretenders will go undetected, thus succeeding in tricking the contestants, it is they who will win $10,000.
