Wish You Were Here (1987)

In a staid English seaside town after the Second World War, sixteen-year-old Lynda Mansell grows up with her widowed father and younger sister. Mature beyond her years because of the untimely death of her mother, Lynda has been swearing constantly from an early age. And with the wink of an eye or the flash of a thigh, she finds love in all the wrong places, much to the chagrin of her cautious father. When her father's best friend seduces Lynda - and leaves her pregnant and alone - this outwardly bold, inwardly vulnerable girl must find a manner to veer from the course of self-destruction... and face the inevitable undertaking of growing up.
