Joel's New Year's Eve whereabouts come under increased scrutiny after his bar buddy Frank admits to Nate and Petra that their alibi was bogus. A visit to a New Year's reveler clears up one issue, but the timing of another remains unclear.

Though he has suspicions that the wrong man is in prison, Nate faces major obstacles as he tries to get a subpoena on a closed case. Eric is dogged by allegations stemming from an earlier mysterious death. An increasingly paranoid Joel weighs his options as evidence against him mounts.

Determined to uncover the missing pieces of the Summit murder puzzle, Petra turns up the heat on JC, Alan and Tom while probing the mining history of several interconnected Summit properties. After getting the cold shoulder from the lead prosecutor on a closed case, she finds herself treading on dangerous ground as the truth--or what she hopes is the truth--is finally revealed.
