A family of three (son, daughter-in-law and single old father) went out for a trip, but they were stranded on an uninhabited desert island because of an accident. Originally, they thought it was an accident, but actually it was a conspiracy made by one person. The family of three lives on this desolate and uninhabited desert island, but they do not know that there has always been a pair of abnormal eyes full of darkness, which no longer monitors them. Taking them as experimental objects, they are conducting a taboo human relationship experiment This article is my new work, inspired by a foreign TV series I have seen before. The TV series is called “mysterious island”, which was published in 1995. If you are interested, you can search and watch it on the Internet.
