Taking Donna to his hideout, Smith realizes that the baby (whom he names Oliver) stops crying when he hears heavy-metal music; he concludes that Oliver's mother lived near a heavy-metal club. Pursued by Hertz, Smith shoots his way out of the hideout and he and Donna head to a nearby club. Above the club they discover an apartment with medical equipment and two dead, pregnant women; Smith concludes that the women were all impregnated with one man's sperm in order to give birth to matching bone marrow donors.
