Jake, Petreski, and the rest are back for another installment of caffeine, snark, and a touch of romance.

It's the start of a new semester and familiar faces are popping up all over - most of them unwelcome. Jake knows Petreski's not going to like his new study buddy and Don has a big decision to make.

Jake's mother will no longer be denied, and it's meet the parents time. Miss Nancy's past comes calling in an all too literal way.

And to top it all off, Petreski's ex shows up and it turns out there's someone out there who Perez hates even more than Jake.

Oh, and somebody gets murdered.

Now with fewer carbs and more caffeine!
