As PCP spreads through Cassie's high school, Val, a new undercover cop, Eddie and Lund are assigned to find and take down the dealers, but when Charles sees Cassie flirting with Val he isn't happy about it – and neither is Eddie. Elsewhere, Lizzie is thrown into a predicament: does she break a promise to protect her friend from embarrassment or should she betray another friend's secret, and possibly ruin her first slumber party.

While Eddie and Jen are walking around the neighborhood, they discover an abandoned baby in a dumpster, and become consume in finding the parents. Lizzie's first crush is one of Tay's friends. Eddie also has trouble dealing with Cassie's feelings for Charles.

Lizzie is kidnapped and held for ransom by two of Donelle's friends, making Eddie reconsider his decision for moving his family to the Heights.

It's been a long, hot summer but with school back in session, life doesn't cool down. Gangs are on the prowl and students are restless, resulting in a lockdown that has life altering implications for everyone in the Sutton family. Through it all, Charles stands by his girl, letting Cassie know he'll always be there for her. She neesd to look no further than him for her protector. But will that be enough to keep her loyal? Can Cassie be trusted?

If pain is too depp and hatred too wide, can peace ever come to Lincoln Heights? Eddie Sutton thinks it can -- if he can just peel kids away from the gangs one by one and get them off the streets. But can Eddie's good intentions outweigh gang loyalty? Is there ever a way out? Maybe not, when feelings are hard, and hurt is left to fester. That's a lesson Cassie is learning as she watches Sage go after Charles. Seeing them together is killing her, but all Cassie ever shows him is her anger. But anger won't win Charles back, and it won't help anyone out on the streets either.
