Anette is tasked with finding concrete solutions to her research findings, Ellen takes control of her life, Nadia reaches her breaking point, and Martina reenters the dating scene.
The series follows a group of four friends who start worrying about their sex lives when one of them, public health researcher Anette, conducts a study entitled 'Sex is a Highway to Health'. The four start to question how decadent Swedish sin has been replaced by the mundane realities of Thursday sex, careers, kids, marriage, divorce and the never-ending struggle to stay young, fit and sexy.
