chunk: The unnamed Narrator (Edward Norton) is a traveling automobile recall specialist who suffers from insomnia. One night, he visits a support group for testicular cancer victims, where they assume that he, too, is a victim, and he spontaneously weeps into the nurturing arms of another man, finding a "freedom" that euphorically relieves his insomnia. He becomes addicted to participating in support groups of various kinds, always allowing the groups to assume that he suffers what they do. However, he begins to notice another impostor, Marla Singer (Helena Bonham Carter), whose presence disturbs his bliss. The two negotiate to avoid their attending the same groups, but, before going their separate ways, Marla gives the Narrator her phone number.
