As the saying goes, "the golden house and the silver house are not as good as your own doghouse". There is no place in the world that can be compared with home. The protagonist's home is in a dilapidated old people's home near South Beach in Miami, USA. They are four old men in their twenties, named Bobby Bartellemeo, "Black bat" Joey Pistella, "Steel Brick" Mike Donatelli and "Big mouth" Tony Donato. Despite their poverty and poverty, they are not all experienced members of the mafia when they are young. On the white beach, sexy model cavort is scratching her head to take the cover photo of haute couture magazine, but they don't want to appreciate it because they are about to be evicted from the home for the elderly. Opposite the old people's home is a bustling business district with a good location. The landlord plans to drive the old men out and renovate the old house so that they can attract more high-end tenants, charge higher rents and make more money. Although it is in the twilight years, the old people are not old at heart. In order to save the home for the elderly, that is, their home, the four decided to return to their old jobs. They conceived a watch.
