Celebrated war correspondent Marie Colvin, known for her fierce dedication and willingness to bear witness to the horrors of conflict, works for The Sunday Times in London. Renowned for her distinctive eye patch, a result of an injury sustained while covering the civil war in Sri Lanka, Marie is a complex character—a woman grappling with the toll her career takes on her personal life and mental health. The challenges of PTSD and the strain on her relationships at home contrast sharply with her fearless approach to journalism in the world's most dangerous hotspots. Marie's story is one of unyielding commitment to reporting the truth, often at great personal risk.

In the depths of war-torn landscapes, Marie partners with freelance photographer Paul Conroy to cover the most volatile conflicts of the early 21st century. Together, they venture into rebel-held areas in Syria during the siege of Homs, exposing the scale of the humanitarian crisis and the suffering of civilians trapped by the conflict. Their relationship highlights the bond forged in extreme circumstances and the importance of collaboration in unveiling the realities of war. Despite the physical and emotional scars that accumulate with each assignment, Marie's pursuit remains unshaken: bearing witness and giving a voice to the voiceless, all while navigating an industry and a world often ambivalent to her mission.
