Mare Winningham stars as a sister determined to find out the truth in this fact-based made-for-television drama. Patricia Arquette stars as an FBI informant who has a secret affair with a married agent (Stephen Webber). When her older sister Dana (Winningham) admonishes her to be careful, she refuses to heed the warning and plunges deeper into the relationship, which unfortunately has deadly consequences. TV-movie veteran Winningham is good as always and Arquette and Webber are a believable duo. ~ Bernadette McCallion, Rovi
