Risk (2001)

It's the quiet ones you have to watch.

Three people discover jealousy and larceny are a dangerous combination in this tense drama. John (Bryan Brown) is a veteran insurance investigator who succumbs to temptation and veers towards the wrong side of the law. With the help of novice con man Ben (Tom Long), John hatches a scheme to substantiate false claims by taking a percentage of several questionable claims his firm has settled for a fraction of their usual worth. John and Ben are assisted in their illegal business by Louise (Claudia Karvan), a lawyer with a cocaine problem who is also John's lover. But when Louise becomes involved with Ben and demands a bigger share of the money, their already-shaky confidence game begins to collapse.
