David's return at the end of volume 15 Katchoo's chamboule, and these are our two friends who are going to meet Casey in Las Vegas, the city where we can get married on a head-on... But between two nights and the pursuit of a psychopath, this will be the opportunity for Katchoo to take stock of his feelings and take a new start. Meanwhile, Brad discovers Francine's tattoo and does not appreciate that his wife is engaging in this kind of fantasy without telling him about it. The couple will move to Houston where the new post that Brad has picked up (and incidentally Katchoo) is located. And could it be that the infamous Freddie Femur finally found love?
