Ex-con George, expecting to be repaid after taking a fall for his crime boss, is reduced to driving classy call girl Simone to her jobs at London's finer hotels. Despite their differences (he's a poorly-educated, unattractive, and unsophisticated bigot; she's a beautiful, elegant, and intelligent black woman), George falls in love with her and agrees to help locate one of her old friends, a junkie still working the streets for a dangerously violent pimp.
