Agent Mike Slade has been tracking Cartel Lieutenant Miguel Ayala for months, but each time he gets close to arresting Ayala, Slade and his team of DEA agents find themselves walking into scenes of carnage instead of drugs, money, and Ayala. Assistant United States Attorney Staci Everly is ready to prove she can tackle difficult cases. She is assigned to aid Agent Slade in his quest to bring down Ayala. Working together, they discover there is a mole, tipping off Ayala and preventing Agent Slade from collecting the evidence needed to put Ayala away. As they get closer to discovering the truth, Staci's life becomes in danger, therefore placing the case against Ayala in danger. Agent Slade must now work to find the mole and stop him, protect Staci, and protect the case, as well as get the evidence against Ayala in order to bring down the cartel's operation in Missouri. As they make progress in the case, Agent Slade and Staci Everly also find themselves dealing with feelings they did not want. As they close in on the mole and Ayala, Mike Slade and Staci Everly are caught in a final showdown that could end in one or both of them being killed and where they are forced to acknowledge their love for one another.
