His company is also going through a difficult time but the man gets the fundamental help of his sister Barbara and his brother-in-law Giulio, who offer him a considerable sum of money if he will take care of their son's dog, since they will be abroad for some time. Too bad Valerio can't stand dogs, but when he's forced to accept and starts taking care of Spugna: it will be the beginning of an experience that will change him in an unexpected way.
