chunk: In May 1962, on the Italian ocean liner Antonia Graza, dozens of wealthy passengers are dancing to the song "Senza Fine" sung by Francesca, an Italian singer. A young girl, Katie Harwood, is sitting alone, until the ship's captain offers to dance with her. Elsewhere, a hand presses a lever that unravels a thin wire cord from a spool. The spool snaps and the wire slices across the dance floor, bisecting the dancers.
