Marta Kober (Friday the 13th: Part II) has a small role in this whodunit thriller about a serial killer who kills for political gain. It's nothing original, but I guess it's pretty typical of these 1980s thrillers.
Here is a small synopsis of Marta's character that I found on SmartFellowPress.com
Marta Kober is Billy's 16-year-old prostitute girlfriend Toni. She has aspirations of living as a high priced prostitute couple with Billy in a Brentwood condo. Her body is found in a Riverside bus station.
