Nicole Kidman has done a lot of different things in film: she's been a horny schemer in Malice, a strong-willed young Irish immigrant in Far and Away, she was even Virginia Woolf in The Hours. But in television, she specializes in women who are rich and haunted. Haunted by a nightmarish marriage in Big

Little Lies, haunted by the possibility that her husband is a murderer in The Undoing, and now haunted by a tragedy in Expats, the splashy Amazon series adapted from Janice Y.K. Lee's 2016 novel The Expatriates, about three American women who are not from Hong Kong, but live there.

Kidman plays Margaret, a landscape architect. When we meet her, Margaret seems to be in a fog, barelyengaged with her son and daughter, or with her husband, Clarke (Brian Tee). Clarke's job is the reason the

 family has come from New York to Hong Kong, and at the opening of the series, he's secretly seeking comfort in a church because something bad has happened. When an innocent question about a child named "Gus" causes Margaret to flee a room, the nature of that something bad begins to emerge.
