“A satisfying, well-acted war thriller with surprising dramatic depths, Guy Ritchie’s The Covenant tells a solid story with impressive restraint.” [Source]

Despite being a major war film, the movie has some serious emotional connections with the characters. John Kinley (Jake Gyllenhaal) and his interpreter, Ahmed (Dar Salim), naturally form a bond that is unbreakable after an ambush.

Ahmed risks his life to save John’s, and when John learns that Ahmed and his family’s safety are compromised in Afghanistan, John decides to go back to save them.
