The rules for a perfect vacation: never set off without taking your rubber dinghy with you, never set off leaving your dog behind, and -most important- never book the same summerhouse together with other people. Aldo, Giovanni https://we.tl/t-3zF3Qfaf1Z and Giacomo are leaving for summer holidays, they don’t know each other, and their lives and families could not be more different: the fussy and meticulous guy, whose business activity is however disastrous; the successful doctor struggling with a son in teenage crisis; the deadbeat hypochondriac with a dog called Brian and a passion for Massimo Ranieri. Three very distant ways of life, accidentally meeting on a small island off the Italian coast: same beach, same seaside, but especially same rented house. The clash is unavoidable and very amusing: different habits, two of the children falling in love, the three wives starting off with wrong foot but ending up dancing together in a summer evening – and three recent friends chasing a son on the run. Aldo Giovanni and Giacomo tell us a story about friendship and feelings, as in their most beloved and esteemed film tradition.
