Some wolves attack when their prey is at its weakest. Some charge fiercely. Others...knock softly.

When Greg Slater returned home from college for winter break, his whole world changed. After rescuing his high-school sweetheart, Tina Dibari, and helping sentence his best friend, Rene Dibari, to life in prison, Greg fell in love for the first time.

Fifteen years later, life isn't easy, but Greg and Tina are working on their marriage. But an old fear has come back to haunt them...

Rene has escaped prison, and he's thirsty for revenge.

As shocking truths unfold, Greg and Tina face a ripple in their faith and in their home. Tina starts doubting her faith and seeks comfort in a friend with lustful intentions. Meanwhile, Greg struggles to navigate this new unrest in their relationship.

Unfortunately, evil stops for no one, and three very different wolves are after the Slater family.

Will Greg and Tina's love be enough to keep them together, and-more importantly-will their faith hold true when the wolves come knocking?
