Sharon doesn't think she can ever love again, but what Johnny offers seems like a dream come true. His charm and kindness shine so bright, Sharon can almost believe he's changed. As the search for her father continues to frustrate and tensions escalate with Cassie, Sharon wonders if leaving it all behind for a life with Johnny will save her crumbling heart. Will the truth set Sharon free? Or it will it be the final blow to her sobriety?
