Hollywood, de jaren 20. De filmindustrie ondergaat de transitie van zwijgende films naar films met gesproken tekst. 'Babylon' volgt de opkomst en ondergang van enkele personen, waaronder Nellie LaRoy en Jack Conrad, tijdens een tijdperk van ongebreidelde decadentie en verdorvenheid in deze industrie.
