Estranged half-siblings Angela and Nate reunite for a 4th of July celebration at their family's cabin in the woods, along with their friends. The siblings try to be civil and have a good time, but it doesn't take long before they argue and a drunken Nate starts reading from a copy of The Declaration of Independence. The argument becomes physical, sending brother and sister into the snack table and covering them both - and the Declaration - in beer.
