Ty Hackett, a young war veteran, starts working as a security guard for the Eagle Shield armored truck company. Struggling to make ends meet and support his younger brother Jimmy, Ty is quickly befriended by his fellow guards, particularly Mike Cochrane, who becomes somewhat of a mentor. Facing mounting financial pressures, Ty reluctantly agrees to participate in a heist proposed by Mike and endorsed by the rest of the crew. The plan involves stealing $42 million from one of their own trucks during what is supposed to be a routine delivery. The guards believe they can make the robbery look like an external attack, thereby diverting suspicion away from themselves.

As the plan unfolds, tensions rise within the group, and unforeseen complications start to unravel their carefully laid scheme. Ethical questions begin to plague Ty, and he wrestles with his conscience while trying to maintain his loyalty to his colleagues. The situation becomes increasingly precarious, pushing Ty to make critical decisions that could either save or sink them all. The dynamics within the group become strained, leading to confrontations that test their trust and resolve.
