***SPOILERS*** We get a tour of the NYC Subway System circa 1953 with private investigator Mike Barnett being put through the ringer by mobster Frank Collins in finding an envelope with $200,000.00 in uncut diamonds that one of his goons accidentally left on a subway car at the 34th street station. Barnett was just minding his own business when Collin's man left the seat next to him and checked out leaving the 200 G's worth of diamonds behind. First having Barnett kidnapped and forced to reveal the serial number of the subway car he was on Barnett breaks away and runs down to the Brooklyn Bedford Ave subway station where he runs into transit detective Joan Ashford who arrest him for her feeling that he's trying to pick her up in Barnett thinking that she's a hooker.
It's later when Barnett proves that he's on the up and up that the two together with the rest of the NY transit police start looking for the missing diamonds with Collins and one of his top goons Joe Schmo not far behind. It's at the train yard in the Bronx that Barnett gets the information he's looking for in what the serial number of the subway car is from train dispatcher Joseph Lebermen but now has both Collins and Joe Schmo to contend with who've been following both Barnett and transit detective Joan Ashford every step of the way.
It didn't take much for Barnett and Joan to dispatch these two clowns, Collins & Joe Schmo, with a squad of transit police alerted by dispatcher Leberman coming to their rescue. Collins proved to be just as stupid if not more so then the absent minded person he entrusted the diamonds with. That by him not realizing that Barnett had everything covered in his quest for the lost or missing diamonds which Collins wasn't smart enough to figure out.
