Brave Eye (2018)

Sergeant Hardrock loses three of his fellow soldiers and his left eye in an ambush. While recovering from surgery, he opens a third eye that makes him see the ghosts of his comrades. Each of them as a mission for Hardrock that will complete their respective lives. As he sees the darker and more complex side of his comrades, Hardrock gains a new perspective in life. Even if he only has one eye.
