Edgy, ecological TV thriller from the same stable that made 'Life on Mars' and 'Spooks'. This highly topical drama focuses on the lives of two friends in the oil industry, whose relationship is tested to the full by increasing environmental concerns and the greed of big business. When the head of Arrow Oil retires unexpectedly, Tom McConnell (Rupert Penry-Jones) is asked to step up, with the backing of best friend Mack (Bradley Whitford). Having had a relatively easy ride thus far, Tom suddenly finds himself having to deal with a range of threatening situations, from oil workers in Saudi Arabia being murdered, to getting served with a writ for environmental damages by the Arctic Inuit. As his problems worsen and his personal and professional lives collide, a climate change conference forces him to raise doubts about Mack's loyalty, especially when claims surface regarding Arrow's complicity in the Saudi murders.
