In a small Texas town in the early 1970s, two undercover narcotics officers, Jim Raynor and Kristen Cates, team up to infiltrate and dismantle a powerful drug ring. Jim is experienced and resilient, while Kristen is new to the world of covert operations. As they dive deeper into their roles, they immerse themselves in the drug culture, blurring the lines between duty and reality. Their mission demands they pretend to be frequent users to gain the trust of drug dealers, with their primary target being a local kingpin. As they adopt their new identities, the pressures mount, and they begin to struggle with addiction.

Their once clear objective becomes clouded, and their personal lives start to deteriorate under the weight of their double lives. The bond between Jim and Kristen deepens, both as partners and as two individuals grappling with the moral and physical consequences of their assignment. With the increasing dangers and temptations, they find themselves at a crossroads where their integrity, sanity, and survival are tested to the limit. As suspicions and conflicts arise from all sides, the escalating turmoil ensures that nothing remains the same.
