The last thing Maddy expects is to come home and find her ex throwing down with her new boyfriends. She thought she had left Mike in her past, but is sudden return may ruin everything. He saved her once, and now she feels obligated to return the favor. But misunderstandings keep cropping up, and she fears Mike is up to his old ways, using her new home as a front to move his drugs. He puts everything she's worked for at risk, but now that he's moved in, how can she force him to leave? Meanwhile, her guys are still running an undercover investigation that puts all of them in danger if they're caught. Someone is threatening to harm those close to Cody, and they've already proved they'll follow through. Then Maddy starts to feel off. Is it her lingering illness, or is something else to blame? Can this group of troubled college students stay together? Or will outside forces pick them apart, one at a time?
