The Major Crimes division faces a new challenge as they work to solve the murder of a dog that was left a 20 million dollar estate by his deceased owner. With the help of wannabe detective Jonathan Baird, aka Dick Tracy, the case takes a new turn as the squad begins to suspect foul play in the death of the dog's owner, a wealthy heiress.

When a foreigner is found murdered inside his hotel room, the squad must work quickly to find the killer while avoiding any international repercussions when a U.S. diplomat becomes involved in the case. While everyone is busy with the case, Rusty tries to figure out how to share a big secret with the squad.
