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.

Growing up, Catherine Holt always dreamed of marrying a loving, brave firefighter...just like her daddy. Now, after seven years of marriage, Catherine wonders when she stopped being "good enough" for her husband.

Regular arguments over jobs, finances, housework, and outside interests have readied them both to move on to something with more sparks.

As the couple prepares to enter divorce proceedings, Caleb's father challenges his son to commit to a 40-day experiment: "The Love Dare." Wondering if it's even worth the effort, Caleb agrees-for his father's sake more than for his marriage. When Caleb discovers the book's daily challenges are tied into his parents' newfound faith, his already limited interest is further dampened.

While trying to stay true to his promise, Caleb becomes frustrated time and again. He finally asks his father, "How am I supposed to show love to somebody who constantly rejects me?"

When his father explains that this is the love Christ shows to us, Caleb makes a life-changing commitment to love God. Andówith God's helpóhe begins to understand what it means to 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.
