Based on the true-life romance of '60s Chicago mobster Sam Giacana (Turturro) and song bird Phyllis Maguire (Parker), one of the wholesome Maguire Sisters. Naturally, getting involved with a crime boss did little for her image and Maguire's career hit the skids while Giacana's volatile jealousy brought unwanted attention from both fellow gangsters and the feds. (He was murdered in 1975 but had broken off with Phyllis before that). The real Maguire denounced the inaccuracy of the TV production. Suggested by William F. Roemer, Jr.'s book "Roemer: Man Against the Mob."
