In the 1970s, a group of teenage surfers from a tough neighborhood known as "Dogtown" in Venice, CA, pioneered a revolutionary new style of skateboarding. Riding the waves at the Pacific Ocean Park pier, the Z-Boys, known for their aggressive style and hard street attitude, combined the death-defying moves of surfing with the art of skateboarding and became overnight sensations and local legends. With empty pools as their canvas, the Z-Boys paved the way to what is now referred to as "extreme sports," and created a lifestyle that spread infectiously to become a worldwide counterculture phenomenon. But all of this fame would take its toll on the friendships that they thought would last a lifetime, as the sport that started out as an afternoon hobby turned into big business.
