At work, inside burning buildings, Capt. Caleb Holt lives by the old firefighter's adage: Never leave your partner behind. At home, in the cooling embers of his marriage, he lives by his own rules.

​

After seven years of marriage, Caleb and Catherine Holt have drifted so far apart that Catherine wishes she had never married. As the couple prepares to enter divorce proceedings, Caleb's father challenges his son to commit to a 40-day adventure he calls "The Love Dare." Wondering if it's even worth the effort, Caleb agrees, but more for his father's sake than for his marriage.

​

Along the journey, however, Caleb makes a life-changing commitment to love God ... and, with God's help, truly love his wife.

​

But is it too late to fireproof his marriage? His job is to rescue others. Now Caleb Holt is ready to face his toughest job ever ... rescuing his wife's heart.
