The motive, they suspect, is to prevent Rita and her dance partner Ken Satillo from winning the first place prize of $30,000 in the Fortune roller dance contest. However, Kelly and Tiffany uncover the real motive as they discover that Rita is the heiress to the wealthy Lathrop real estate empire. Rita's stepmother agrees to pay the million-dollar ransom. The Angels discover that Satillo and roller dance promoter Freddie Fortune are the most likely suspects. They see Satillo pick up the ransom and follow him back to the roller rink and Rita. Freddie is captured in his D.J. booth and Ken and Rita are allowed to perform their last duet before he must go to the slammer.
