There is a movie I watched when I was younger (early 200os maybe late 1990s) that I think is Italian, but not totally sure. The first scene has three kids playing at the beach when a larger group of kids (I think 7?) come and start bullying them. The bullies make one of the original three step on an urchin. Then one of the bullied kids tells his dad, who takes him to the bullies house and tells the bullies father. They go to the backyard and the kid watches as the dad punishes his son for the bullying. And the three original kids make more friends and try to beat up the seven that bullied them, who then get more backup and so on so at the end on the beach you've got these two large groups facing off. I think there was a love story as part of the plot somehow too, but I don't remember much more than this. It's been bugging me for ages and I don't know anyone who knows what I'm talking about! Thanks!
