In a world where journalism is being attacked, Marie Colvin is one of the most famous war correspondents of our time. Colvin is a rebellious and completely fearless spirit, motivated to give voice to those silenced, constantly testing the boundaries of courage and bravado. After being hit by a grenade in Sri Lanka, she wears a distinctive patch on her eyes, and it is still as comfortable to drink martini with the London elite while facing the dictators. Colvin sacrifices loving relationships, and in time, her personal life begins to fall apart as the trauma she witnessed leaves deep traces. However, her mission to show the real cost of war, together with renowned war photographer Paul Conroy, engages in the most dangerous mission of their lives in the Syrian city besieged by Homs.
