On a one-week Mediterranean pleasure cruise aboard the yacht of movie producer Clinton Greene (Coburn), the guests include actress Alice Wood (Welch), her talent-manager husband Anthony (McShane), secretary turned talent agent Christine (Cannon), screenwriter Tom Parkman (Benjamin) and his wife, Lee (Hackett), and film director Philip Dexter (Mason). The trip is, in fact, a reunion; with the exception of Lee (who was "sick of Santa Barbara"), all were together at Clinton's home one year before, on the night a hit-and-run accident resulted in the death of Clinton's wife, gossip columnist Sheila Greene. (Yvonne Romain, a former Hammer horror actress, appeared as Sheila Greene in a cameo performance.)
