Mike Giardello (Giancarlo Esposito), son of Gee and FBI agent faces a desperate man (Ron Eldard) who threatens to kill himself and his children, and insists on having Mike as the negotiator. Gee Jr has to talk him out of the increasingly dangerous situation.
Lines of Fire features solid writing and interesting performances by Esposito - who is much better here than in the rest of the season - and Eldard as the suicidal father. Although the excuse to put Gee Jr in the spotlights feels contrived... just like in the rest of the season, after all.
The Mike Giardello/Gharty duo - the confident, self-righteous young man and the bitter bigot - works well, like in the surprisingly good Shades of Gray; the uncompromising ending is memorable.
