'18 To Life' is about a couple that does the unthinkable in the name of love: they run off and get married at the tender age of 18. Their parents-next-door neighbors and polar opposites-are less than thrilled and even their peers disapprove. As Tom and Jessie struggle to become man and wife in a world that still views them as kids, the tension between their families adds a dose of biting humor to their sweet love story.
