"Family or Fiancé" follows the dynamics between eight engaged couples who bring their disapproving families together under one roof. The families only spend three days with each other, and the clock is ticking as the couples decide if they're going to tie the knot. Serving as the voice of reason in this chaotic time is relationship expert Tracy McMillan as she works to help the families confront their concerns. McMillan works with these newly engaged couples to strengthen their bond, air their differences, and reveal their true selves to their families. At the end of the third day, families are given their chance to speak. When that ends, the couples then have to make the ultimate choice -- "I do" or "I don't."

The conflict arises during their first family meeting when Ashley shares details of their intimate life with Keron's mother, leading to significant tension and judgment. The episode, hosted by relationship coach Tracy McMillan, explores whether the couple can overcome their families' differences and concerns to get their blessing for marriage.
