As a firefighter, Captain Caleb Holt (Kirk Cameron) patterns his professional life after these words. But as a husband, he patterns his role in marriage after his own wants and needs. Arguments over jobs, finances, housework and outside interests are a regular occurrence in his home, so he is not surprised when his wife, Catherine, asks for a divorce.
As the couple prepares to enter divorce proceedings, Caleb’s father challenges his son to commit to a 40-day experiment: “The Love Dare.” Though reluctant at first, Caleb accepts the dare and gradually begins to realize that it is impossible for him to truly love his wife without the love of God.
Though Caleb desperately tries to win back his wife’s heart, Catherine resists his efforts, too hurt by his previous actions to give him a second chance. When Caleb reaches the end of his rope, only a miracle can revive the cooling embers of their marriage.
