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.
Two stories run on parallel lines in a nocturnal Rome. Marcello is an easygoing sixty-five-year-old film producer trying to convince a beautiful actress to accept a part in a film.

Marcello talks about his experience working with Fellini and Mastroianni during the wonderful years of DOLCE VITA; this strongly contrasts the city experienced by the immigrants.
