House of games2

Back in her normal routine, Margaret continues to think about her night at the House of Games. She returns, proposing to Mike that she follow him around, learn the ins and outs of his world, perhaps write a book on the experience. Mike is skeptical but agrees. He shows her first-hand how a con game works. Her fascination grows. The pair end up going to a hotel room and making love.
Mike mentions that he has a role in another con that night. Margaret begs to tag along. Mike, his associate Joey (Mike Nussbaum), and their mark (Walsh) come upon a briefcase of money that someone seemed to have accidentally left on the street before getting into a cab. The three men go to the mark's hotel room to keep an eye on each other and discuss what to do with the cash.
Mike confides to Margaret that the $80,000 in cash is real, borrowed from the mob and due back the next day. The plan is to have the mark propose paying Mike and Joey a percentage in exchange for taking the briefcase, but then they will switch the case at the last minute.
The mark does as planned, but Margaret sees and hears what no one else does — that he has a gun on his belt, and that he is planning with others over a two-way radio to arrest the trio. Margaret warns Mike and Joey that the mark is a cop and it's a trap, and she is desperate not to get caught herself. A scuffle develops and the cop/mark is killed when his gun discharges. Mike makes a run for it with Joey and Margaret. They steal a car and escape. But the briefcase is nowhere to be found — it's been left behind in the commotion. Mike must leave the country fast because the mob will turn them all in for the murder if they fail to return the mob's money. Margaret, who has now fallen for Mike and fears for his safety, as well as her own, offers to replace the $80,000.
