Christian Wolff (Ben Affleck) is a math savant with more affinity for numbers than people. Behind the cover of a small-town CPA office, he works as a
freelance accountant for some of the world’s most dangerous criminal organizations. With the Treasury Department’s Crime Enforcement Division, run by Ray
King (J.K. Simmons), starting to close in, Christian takes on a legitimate client: a state-of-the-art robotics company where an accounting clerk (Anna
Kendrick) has discovered a discrepancy involving millions of dollars. But as Christian uncooks the books and gets closer to the truth, it is the body count
that starts to rise.
