Two young pirates come together to look for diamonds and gold, but ultimately find something far more precious: friendship. The gnarled tree on the hill sometimes turns into a pirate ship. A rope serves as an anchor, a sheet as a sail, and Sam is its fearless captain. But one day another sailor approaches, and he's not from Sam's street. Can they bridge their differences to become friends?
