A bank robbery gone wrong turns into a bizarre hostage situation for a father-and-son police duo not used to solving serious crimes.

Jack and Jim lose sight of the robber; eager to get the case back on track, they interview a couple of witnesses who may know more than they let on.

Police begin to suspect Zarah, the banker, of something; meanwhile, Jim and Jack welcome a surprise guest, and Lennart turns on the charm.

Julia and Ro's romantic back story comes into focus; in the present day, Ro goes missing just as a very pregnant Julia needs her most.

After ruling out other suspects, the police focus their suspicions on the one person they can't seem to find.

Tensions -- and tempers -- run high when the truth about what actually happened during the robbery is finally revealed.
