In this powerful story based on real events, we meet Lee Strobel, a skeptical and atheist investigative journalist working for a major newspaper. His life takes a turn when his wife, Leslie, decides to convert to Christianity following a transformative spiritual experience. As Lee observes the change in her, he can't help but feel threatened and alarmed by this new faith that seems to have changed her for the better.
Determined to prove that Leslie's faith is unfounded, Lee embarks on a fierce quest to dismantle Christianity. He begins interviewing experts, from biologists to archaeologists, in the hope of gathering the evidence that will turn his wife back to skepticism. However, what initially appears to be a straightforward case becomes an internal battle for Lee as he confronts evidence that challenges his beliefs.
With each dialogue and new discovery, Lee must question not only the foundations of the Christian faith but also his own values and his relationship with Leslie. In this intense journey of introspection, he finds himself caught between his desire to protect his wife and the growing conviction that there may be something more than what he has always believed. Focusing on the pursuit of truth, the film explores the struggle between faith and reason, leaving both Lee and the viewers in deep reflection on what it truly means to find the truth.
