We see a raft full of people in a rough river and see lots of stills.  We see the people in shots.  We see the title screen.  We see a helicopter over a river.  The raft turns over and a lady laughs.  We see a bus driving on the street.  We see the canyon from afar.  We see a tunnel and a speedboat.  We see still shots of the rafters.  We see the ending title screen.
