Walter Bullitt's New York, 1968. Part-time U S government provocateur and full-time hepcat, Walter isn't keen on the assignment his employers are trying to toss him - no need to mix with the Kennedys if you don't have to.
He also hopes the ghosts he's been talking to lately are only a side-effect of the recreational drugs. Then two women from a different New York show up and tell him they aren't. Now, Walter saw 'When Worlds Collide' but he never thought he'd be starring in the road show, especially when one world is his and the other, invisible - at the moment.
