Brian, Peter, and Joe are three old friends ridge running in the Sierras. Now, they are adults with jobs, but they make time to do this together to help them reconnect in the midst of their busy lives. Last year, Joe spent most of his time in the hospital because he suffered an accident. He lost many neurons in his brain, but the doctors helped him grow them back. Now, he suffers mild confusions with words and seems out of it sometimes, but he’s mostly okay. Together, Brian and Peter try to help Joe relearn what he lost as they travel through the woods.
