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.
When Wendy does a documentary on why marriages work or fail, the couples do interviews that forces them to rethink their relationships. Meanwhile, Tom just wants to fix a stubborn ceiling leak in the attic.
Tom and Jessie finds jobs at the same book store, but Jessie is hired for the managing position and Tom is just the janitor. Ben discovers yoga to the dismay of Judith and Phil fights the squirrels running rampant in his backyard.
When Tom's cruel Grandmother discovers he's married, she croaks on the spot, leaving a guilt wracked Tom to invent nice things to say at her Eulogy. Phil builds a gate in the fence dividing their properties so that the Bellows can visit their Grandma's shrine.
