McClaren School of Law student Ken Malansky is in a recently rocky relationship with Kimberly McDonald. Frank Wellman Jr. also has romantic feelings for Kim, and now all three of them are together in a class taught by Perry Mason.
Kim's roommate, Donna Lehman seems to like the drama when she tells Ken that Frank has assaulted Kim which then results with Ken rushing off for a confrontation. In a darkened room it is discovered that Ken is together with Frank... dead.
In spite of the victim being the son of Perry's friend Frank Wellman, Sr., Mason agrees to defend the accused student.
