Luke and Manny have their first day at high school, which proves to be harder for Phil and Gloria than for the boys. Elsewhere, Claire makes her big return to the workforce at Jay’s closet company and is a little rusty on her first day, and Cam starts a new substituting gig at the high school, leaving Mitch to try to juggle Lily’s first day in 1st grade and a very important meeting at work.
A car is pulled out of the river with a dead woman inside. Lassiter and Juliet are investigating the crime scene. Shortly after, Shawn and Gus arrive on the scene. Shawn looks more closely in the car and determines that the dead woman wasn't in the car alone, and therefore hypothesizes that she was murdered.
Gus tells Shawn he has to get to tap class. Lassiter overhears and inquires about it. At the tap class, Gus is surprised to see Lassiter show up. Lassiter insists Gus let him take the class with him as a means to follow through on his therapist's orders to try something new.
