At first, he only finds that they are well hidden and leery of sharing their horrific stories, but he also discovers that he's falling in love with their homeland. He is intoxicated by Moscow's brooding, ironic atmosphere, its vast reservoir of entrepreneurial energy, its otherworldly churches and majestic subways.

So he blithely accepts a big win when a chance meeting with a lovely aspiring actress leads not only to romance but also to her grandfather, a concentration camp survivor who does actually want to share his story.
