DURING THE VIETNAM WAR, GIs who managed to survive their tour of duty in one piece - more or less - were flown home in chartered airliners. They called those planes 'Freedom Birds.' This is the story of three young men - from wildly different backgrounds - who meet on such a plane and make a pact to spend three days together in San Francisco. Their goal: to spend every cent of their mustering out money in a party of a lifetime. And they'll get more than they bargained for: because when they land, it is July 1967 - in a time that would come to be known as 'The Summer of Love.' It's a place and time where each young man will have to confront the ghosts who followed them home from the jungles of Vietnam and contemplate a future none of them had imagined.
