S4, E11: When two girls from Tiffany's sorority disappear, the Angels find themselves back in college trying to unravel a suspected white slavery ring. English professor, James Fairgate, with a reputation as a womanizer, is considered a prime suspect. So is footballer Steve Fitzpatrick, who harasses sorority women. Kris audits Fairgate's class and cautiously questions him about his possible involvement in the case. Bosley and Kelly pose as pro football scouts also to question Steve. Tiffany escapes an unseen assailant in the locker room but later, she is kidnapped from a party. Satisfied that Steve is not involved, and acting on Kris' information, Bosley and Kelly follow Fairgate to a beach house where Tiffany and the other girls are being held captive. It seems that the sorority housemother, Barbara Kay, heads a white slave trading ring. Tiffany awakens from a drugged stupor and battles with Fairgate and the guards--dropping them all with karate blows. The Angels arrive to apprehend the group including Barbara Kay.
