This millionaire comes out well from the treatment and his conscience is now in a young and healthy body, so he can enjoy life. However, soon everything begins to twist, because as we have said before, it is an experimental treatment.
It all starts when you discover the details about the origin of your new body, something you do not like too much, so you will start to research on your own to find out what the treatment actually consists of.
