Sam has flown to Colorado from New York to visit her brother Tom, and to meet his much younger fiancée, Dee-Dee. But it turns out she has other reasons as well-she tells Tom she's learned something specific about Dee-Dee, something he should know. He's not interested in digging through her past, though, and instead turns the spotlight on Sam and her own hang-ups. Sam, impatient with being examined herself, tells Tom that what she flew out to tell him is that Dee-Dee used to star in pornographic videos. Tom decides to take the high road and not to let Dee-Dee's youthful indiscretions poison his view of her. But Dee-Dee's surprising reaction when he confronts her sends him over the edge, and the situation quickly becomes dangerous.
