Dwight and Whitehead team up to investigate a missing-persons case, only to be stunned when a nun emerges as the main suspect. Meanwhile, Sutton happens upon an abandoned baby and reaches out to Dwight's mother for a tutorial on basic baby care.

Dwight goes sleuthing when three gun-toting thieves rob a party boat, but there are ripple effects when the case involves one of Dwight's oldest friends. Fallout from the investigation allows Dwight to reconnect with an ex-flame and perform music with an old bandmate.
