Nobody's Fool (1986)

Synopsis
This sharp drama is about the trials and tribulations of a young woman defeated by her past, yet tempted to overcome it through a meaningful relationship. Cassie (Rosanna Arquette) works as a waitress in a southwestern town. Not that long ago, she stabbed her lover (and the father of her baby) in public, and even though he recovered, she did not. The most immediate result of her action is that she gave away her baby, and the next, more severe result is that she lost all of her self-respect. Now she takes care of her mother and younger, offensive brother and also dallies on and off with her ex-lover -- who is married. Then Riley (Eric Roberts) comes into town for awhile with a theatrical troupe and he falls for Cassie. He is only in town for a short period of time and that may or may not be enough to convince Cassie to leave with him when he goes. ~ Eleanor Mannikka, All Movie Guide
