One year on from taking up residency in Canberra as a Senator in Federal Parliament, Cleaver (Richard Roxburgh) has old foes and new: Cleaver has a new nemesis in the formidable and right wing Senator Penny Evans (Jane Turner) and a new comrade in his COMCAR driver Jakub (Jacek Koman).Nicole Vargas (Kate Box) is now Cleaver's Chief of Staff, and Jack (Tasma Walton) lurks in the Parliamentary shadows, ready to make or break careers. David Potter (Matt Day) has made the transition to a Senator for the Greens and Cal's arch rival and half-brother Joe (Mark Mitchinson) is the Leader of the Government in the Senate who, with Minister for Homeland Security Gareth Morrow (William McInnes), runs the government with an iron fist - or so he thinks.Wendy (Caroline Brazier) is encouraged to set up her practice in the Capital, whilst Missy (Adrienne Pickering) somehow becomes Cleaver's Press Secretary and, with Fuzz (Keegan Joyce) missing in action in Silicon Valley, she (and their daughter Winsome) move in with Cleaver. Cal (Damien Garvey) is fighting his own battles both at home with Jane (Sonia Todd), and at work with the appointment of Caitlin Farquhar (Sara Wiseman) as co-host of his show, until opportunity knocks and he is given both a seat and a ministerial portfolio, with the promise of something more.With a suspected terrorist gas attack on New Parliament House, an unfortunate incident during a visit by US Defence Secretary Linus Potemkin (Anthony LaPaglia), calling for a banking boycott whilst dressed as a zebra, an assassination attempt, a defamation case, the fight to maintain an Aussie ice cream icon, and the ever-rotating Prime Ministers and BuzzStay guests – none of Cleaver's ensuing chaos has abated … but will he step up to help Australia keep calm and carry on – in this the final season of Rake?
