Mike and his fiancé, Julia, claim that ever since their engagement, Mike's ex-wife, Christy, has become "crazy with jealousy" and has been stalking and harassing them.

Christy denies their allegations and claims, instead, that her ex-husband is an irresponsible, overbearing, narcissist, who is poisoning their son against her. She says she couldn't care less about Mike and his new "90-day fiancé," Julia. Christy says she's not stalking or harassing them, and has only used the police to ensure she receives her court-ordered weekends with her son. Can Dr. Phil help these battling exes come to a truce?
