Renowned oceanographer Steve Zissou has sworn vengeance upon the rare shark that devoured a member of his crew. In addition to his regular team, he is joined on his boat by Ned, a man who believes Zissou to be his father, and Jane, a journalist pregnant by a married man. They travel the sea, all too often running into pirates and, perhaps more traumatically, various figures from Zissou's past, including his estranged wife, Eleanor.

Featuring Douglas Fairbanks Jr. and Diana Vreeland, La Belle Epoque evokes "the beautiful era" of 1890-1914, a time in which the wealthy upper classes of the Western world gave themselves over to a life of elegance and taste-making, their eyes closed to the increasing social and political turmoil fermenting beneath the surface of polite society. The program uses period motion pictures, photographs, and sound recordings, as well as the arts and fashions of the period to supplement the spoken memories of the participating interviewees who actually lived... La Belle Epoque.
