Dublado e Legendado no OverFlix. The River Twice is a feature documentary about a group of friends that build Huck Finn inspired junk rafts and set out for a month long trip along the Susquehanna River. But the river winds deep into the heart of Pennsylvania's natural gas industry, and soon they are confronted with the impact this largely unregulated industry is having on the lives of the people they meet along the river.
