They're going undercover...in and out of the bedroom.

Gang members are taking over the halls of Lowell High. Desperate to save her alma mater, teacher Kelly Finch reaches out to at-risk students, even as gang activity continues to escalate. When the superintendent seeks aid from an undercover task force, Kelly is forced to host the most insufferable, most arrogant, most arousing man she's ever met —Lt. "Mac" McNally.

The opinionated pair clashes hard, especially after Mac targets her favorite student. When Kelly lands on the gang's radar, putting her in imminent danger, the intensity of the mission explodes —along with the couple's attraction. Sparks fly in and out of the bedroom, but if Mac and Kelly want to make the school safe once more, it's critical they hide their sizzling covert affair.
