Marina and Alina did not really want to go to the birthday party of their former classmate Dmitry Rogozhkin, whom they themselves married to their mutual friend Tanya. Not only did he turn out to be a loser in life and a lazy person that the world had never seen, he was also "lucky" with his relatives: three older sisters - everything is like a selection of furies! The holiday was "successful": the birthday man went to see the guests off to the bus stop, and on the way back he was smashed in the head, right in his native yard. The next was one of his sisters ... The family, to be sure, is not the most pleasant, but who needed to exterminate her? Very opportunely, Aunt Styopa came to Marina with her pet mini-pig Hryun. His scent is cleaner than a dog's, so the detective pig will definitely help her friends solve these crimes!
