Tom Lisanti identifies this movie as an ABC Wide World Mystery airing July 23, 1974. It must have been re-run, because the captioning on the back of the publicity photo identifies it as a Tuesday Mystery of the Week with an air date of March 23, 1976.

In any event, it's seemingly one of Tisha's "lost movies" and doesn't even show up on the Internet Movie Data Base, although it does appear in the MSN Entertainment and the Blockbuster databases . . .

. . . which identify Tisha's co-stars as Peter Coffield, Tim O'Connor and Charles Dierkop and describe Tisha's character as a flower-child witness to a mob hit who steadfastly refuses to cooperate with the police but is nevertheless targeted for extermination by the mob bosses.

The publicity photo captioning identifies Tim O'Connor (pictured with Tisha in her Theatre) as starring as the District Attorney.
