Tuesday, June 4, 1968: the California Presidential primary. As day breaks, Robert F. Kennedy arrives at the Ambassador Hotel. He'll campaign, then speak to supporters at midnight. To capture the texture of the late 1960s, we see vignettes at the hotel: a couple marries so he can avoid Vietnam, kitchen staff discuss race and baseball, a man cheats on his wife, another is fired for racism, a retired hotel doorman plays chess in the lobby with an old friend, a campaign strategist's wife needs a pair of black shoes, two campaign staff trip on LSD, a lounge singer is on the downhill slide. Through it all, we see and hear R.F.K. calling for a better society and a better nation.—
