The Evergreen sisters have always been opposites with little in common. Martha is married and has the perfect home, family and life. Eliza rents a drab one-bedroom flat, which she shares with her sexy but hapless boyfriend. Until, one day, Eliza walks out on him, the very same day that Martha's husband walks out on her.

Suddenly the Evergreen sisters are united by separation. Eliza is free to pursue the relationships she's always wanted; one that offers stability and security. Martha falls into a relationship that she could never have imagined; it's wild and wicked. Can they find happiness dashing down these new routes or does chasing love only get more complicated when you're running in another woman's shoes?
