In a single day in Los Angeles, a number of interconnected lives are changed forever. A lonely police officer (John C. Reilly) falls in love with a disturbed cocaine addict (Melora Walters). Her father (Philip Baker Hall), the host of the game show "What Do Kids Know'" has terminal cancer and tries to make amends for his past mistakes. A former champion of the show (William H. Macy) struggles to find love while the current champion (Jeremy Blackman) suffocates under the pressures of being a boy genius. An elderly man (Jason Robards) lies on his deathbed, tended by nurse Phil Parma (Philip Seymour Hoffman), while his trophy wife (Julianne Moore) wrestles with grief and guilt, and his estranged son (Tom Cruise), an infomercial host, teaches workshops on how to trick women into having sex. Throughout all of this, past deeds are lamented and strange forces loom in the air.

Director Paul Thomas Anderson's follow-up to BOOGIE NIGHTS is an extravagant, emotional epic inspired by such films as Robert Altman's NASHVILLE and SHORT CUTS, with a sprawling cast of characters searching for love and meaning in a chaotic world. The cast delivers uniformly excellent performances, most notably Tom Cruise's Oscar-nominated role as the sleazy Frank T.J. Mackey.
