Lilly receives new evidence in the 1973 murder of a young female college tennis phenom, Andi, who beat the college's best male player, Fritz, in a high-profile match that might have cost her her life.

Fritz had always been the main murder suspect since he had no solid alibi and had an axe to grind since his loss not only embarrassed him but also cost him major endorsement deals. Fritz was also known to lend Andi towels similar to the one found soaked in poison. However, Andi's huge success rubbed several people the wrong way and the suspect list grows.
