Sam's girlfriend complains that her son, Evan, has stolen a valuable piece of jewelry from her. When Sam takes Jesse to retrieve it, they find Evan in the midst of packing up to leave town. It turns out a brutal loan shark is threatening to break Evans legs unless he steals an 18-wheeler truck filled with black market liquor for him, which leaves Sam and Jesse with no choice but to help Evan with the heist. Things get more complicated when they learn the truck they've just stolen isn't filled with liquor, but something much more dangerous.

Meanwhile, Michael and Fiona search for Nate's killer and when Rebecca leaves town without warning, she becomes their prime suspect.
