The intertwined lives of four couples living in and around Sydney, Australia, form the structure for this drama masquerading as a whodunit. Andrew Bovell freely adapted his play, Speaking in Tongues, opening up the action, as the geography and topography of Sydney and its suburbs become major characters as well. The film opens with a shot of what looks like a corpse entangled in a thick stand of branches -- the title plant, which grows in profusion in Australia. Bovell and director Ray Lawrence take their time in explaining whose body that is and then slowly reveal, with no help from a number of red herrings, how it happened to be there. The principal players are Valerie Somers (Barbara Hershey), a psychiatrist with issues over her child, a murder victim; her husband, John Knox (Geoffrey Rush), an aloof professor whom she suspects of infidelity; Leon Zat (Anthony LaPaglia), a police detective cheating on his wife, Sonja (Kerry Armstrong), who is a patient of Valeries. Zats mistress, Jane OMay (Rachael Blake), is someone he met at a dancing class his wife dragged him to; she is estranged from her husband, Pete (Glenn L. Robbins). Their neighbors, Paula (Daniela Farinacci) and Nik DAmato (Vince Colosimo), try to stay neutral in the OMays split; she works days as a nurse and hes unemployed and minds their children. Suspicion around the disappearance of one character manages to enmesh all of the others. Bovells stories are about secrets, real and imagined, and how they can poison relationships. The film virtually swept all the major awards at the Australian Film Institutes annual ceremony, though its reception in the States was mildly respectful. ~ Tom Wiener, All Movie Guide
