After years of marriage, Joy and Alan Richards find themselves in a sexual rut.
Therapist Joy is trying to find a way to keep her spark with her husband, following a cycling accident which has put their sex life on hold. Suddenly Joy and Alan find themselves drawn to new people, and both are tempted to make the ultimate indiscretion.
With their marriage in crisis Joy comes up with an audacious, unorthodox, but potentially brilliant proposal that will have huge ramifications for the future...
I think the first episode was trying to share how uncomfortable the relationship between the two lead characters was. It may have been a little too effective and that could punish anyone that didn't give Wanderlust time to launch into the main body of the story. (Which I can recommend, as I feel my persistence has already been rewarded by the second episode.)
