Hunky NY lawyer Jeff Daly finally got engaged to fickle Sarah Huttinger, who presents him to her Pasadena family, who all soon take to him, for her sister's wedding to Scott. However, Jeff's clever counting makes Sarah realize her dad Earl isn't her biological father. As more clues from family point toward a suspect - successful author Beau Burroughs - she insists on meeting him. Only like her mother and grandmother, she has a one-night stand with Beau, which may well cost her Jeff.
