Written by acclaimed playwright Nick Payne, previously of "Constellations" and "If There Is I Haven't Found It Yet," "Wanderlust" is an exploration of the relationships of a multigenerational family, looking at how happy relationships are created and maintained and asking whether lifelong monogamy is possible -- or even desirable. Emmy and Golden Globe winner Toni Collette stars as Joy Richards, a therapist trying to find a way to keep the spark with her husband, Alan (Steven Mackintosh), after a cycling accident causes her to reassess their relationship. As her family, friends, neighbors and clients live their lives, stories of love, lust and forbidden desire emerge.
