In the wake of the Challenger tragedy, Rainbow and her family handle their grief in different ways. Denise realizes that life is too short, so she vows to right all the wrongs she's done in her life (and she's done a lot of bad).

It's the first-ever nationally recognized Dr. Martin Luther King Jr. Day and Paul is speaking at the school assembly about his personal experiences with him. Johan and Santamonica think Paul is going to embarrass them; and being ashamed of her father had never occurred to Rainbow, so they decide to ditch. Meanwhile, Alicia thought she had convinced Harrison to take pro bono civil rights cases on MLK Day to honor him, but he plans to go golfing instead, so Denise steps in to help.
