Court Gentry, also known by the nickname of Sierra Six, is a very experienced former CIA special agent with special skills, he was once one of the best “merchants of death” within this agency. After escaping prison and being recruited by his former superior Donald Fitzroy, Gentry is now a target of the agency he once served, and hot on his trail is an equally good agent named Lloyd Hansen. Aided by colleague Dani Miranda, Hansen will do everything in his power and use all his knowledge to try to capture Gentry.
