A laid-off auto engineer named Marcus, burdened by mounting medical bills for his wife's cancer treatment, stumbles upon a hidden cache of proprietary blueprints from his former employer-a blueprint for untraceable ghost guns that can evade metal detectors. Partnering with a shady network of ex-con fabricators and street-level hustlers, Marcus launches an underground 3D-printing operation, supplying custom firearms to rival gangs, corrupt cops, and high-end clients in the city's elite circles. As profits soar and alliances fracture, Marcus navigates brutal turf wars with a ruthless arms dealer syndicate, an undercover ATF agent infiltrating his crew, and the moral erosion of his family life, where loyalty turns to suspicion and every deal risks exposing his double life.
