Sheila Delaney has one goal in life - to be the best cop she can be - and that means being as good a cop as her father had been. Known as one of the best undercover detectives in her precinct; for that matter, the entire Philadelphia Police Department, it looks a lot like Sheila has achieved her goal. She's often called upon for some of the city's toughest assignments. She uses ingenuity to create a persona that will fit the role she plays while undercover. Even her Captain, admits he never knows what she'll come up with next. Yet, he respects her just as much as he respected her father, a man with whom he'd risen through the ranks. Sheila is called upon to go under cover to break up a drug ring that has strong connections to a supplier in Columbia. A ring that is also connected to the deaths of several people, including other law enforcement officers. They are certain a cop is neck deep in the middle of the entire operation - a dirty cop who may be in their own precinct. The Captain is depending on Sheila to get the information to uncover the person involved. Little does Sheila know how deep her under cover she will have to go as the case has so many twists and turns she might need a program to keep up.
