"Good Luck to You, Leo Grande" follow Nancy Stokes (Emma Thompson), a 55 year-old widow, who is yearning for some adventure, some human connection, and some sex. Good sex. For the first time in her life. Whilst her husband Robert provided a home, a family, something resembling a life, good sex was never on offer. But he's gone now, and Nancy has a plan. As she says, 'there are nuns with more sexual experience than me'. So, being the reasonable, practical woman she is, and as an ex-teacher she likes to be organized, she does some thorough research and hires the services of Leo Grande, a sex worker (or 'sex therapist' as he prefers it) in his early twenties for a night of bliss.
