A mother-in-law stages scenarios where she pretends to drown to test if her three son-in-laws would save her. The first two son-in-laws jump in and rescue her, finding new cars in thanks the next day. However, the third son-in-law does not help and instead watches her drown, thinking he had waited a long time for this, finding a new Porsche from his grateful father-in-law the next day instead.
