Screencaps for Ep 4.18 added

I have just added the screencaps for Underground to the episodes' page. Dan Segal is kind of a clumsy and too good-natured police officer with the heart in the right place. His brother Eddie, however, went the other way - and his parole is at stake since he is about to work for his former boss, Willy Kurland, a local gambling boss, again. Called in by the family, Dan tries to see his brother, but when he arrives at the races, a sniper shoots at Kurland and Eddie, killing both. Just before Kurland dies, Mike levers two important information from him: somebody is moving in the local gambling business and bookmaking, and Dan Segal was just trying to talk to his brother and taking a gun from him. The Chief of Police wants Dan Segal to play the rôle of a cop gone sour, quitting the job at the force and trying to get inside the gambling business as the embittered brother. Mike shall be Segal's primary contact – and although Mike does not really like that idea, he has to join in the game, and one of the game's rules is that nobody shall be informed about the manoeuvre – neither Segal's family nor anyone inside the department, including Steve. Mike's and Steve's official investigations concentrate on the known links between the gambling mobsters, with a young woman named Sunny Malone being the key issue. In the meantime, Dan Segal is trying to get the same kind of information from some underground sources, putting his life at risk several times. When he is about to detain Bobby Waldron, the killer tries to outsmart and kill Dan as well, but Segal can shoot at him first. Our two cops are arriving at the scene, and Dan escapes, leaving Mike to contradict Steve's logical conclusions (i.e. that Dan Segal has obviously gone for revenge). Things are getting even more difficult and dangerous, when Sunny Malone decides to get in touch with the new gambling boss, Frank Garson, in an effort to make something for herself out of the situation. In the final clash, Garson and Johnny Blackwell, another killer in the gambling business, try to shoot down Dan but with the help of Ben Rush, a henchman of the former gambling boss, and the arrival of the police everything turns out good. Steve, however, has a good laugh when he tells Mike that he had recognized Dan's acting long before, leaving Mike astounded - or not.

Filming locations comprise of a colourful potpourri of both, downtown and Bay Area spots. The initial sequence starts at lower Market Street where Dan Segal and his colleague chase the purse snatcher who finally hides in kind of a company underground courtyard or parking. We then switch over to famous Bay Meadows Racecourse in San Mateo (closed and demolished in 2008) where Dan tries to confront his bother Eddie who is eventually shot by Waldron. Dan sees his father in front of his Deli which is located at Bush and Mason Streets, whereas Mike and Steve interview a lady who lived next to Sunny Malone at upper Broadway. Immediately after going underground, Dan hustles a couple of clients at Hyde and Beach, he also talks to Garson's henchman, Blackwell, and runs into Evie at Acquatic Park. Evie's hint leads him to Cable Car Motel, now run by Travelodge, at nearby Lombard Street. Mike meets Dan at the 'Hills of Eternity Memorial Park' in Colma, and then talks to Steve who is on stake out on Russian Hill. Probably a production still from elsewhere was used when Dan hustles another couple of gambling clients in a club and where his girlfriend, Donna, almost quits with him (exterior shot of a 'Round 9 Bar' which I could not find in any directory I consulted). His brother's old friend, Ben Rush, picks Dan up in front of the SFPD headquarters at 850 Bryant Street, that's where his father is also coming to see him. In the epilogue, Mike and Dan are walking up a curved street with freeway ramps in background. This sequence was filmed in South of Market but the exact location does not exist anymore (probably on Clementine between 1st and 2nd Streets).
