As a CIA officer, Evelyn Salt (Angelina Jolie) swore an oath to duty, honor and country. Her loyalty will be tested when a defector accuses her of being a Russian spy. Salt goes on the run, using all her skills and years of experience as a covert operative to elude capture. Salt's efforts to prove her innocence only serve to cast doubt on her motives, as the hunt to uncover the truth behind her identity continues and the question remains: "Who is Salt?"

The question "What watch is Angelina Jolie wearing in Salt?" has partly been answered. One of the two different watches she wears, was identified by Forum member BlackKnight as an Omega Constellation Double Eagle.
