Tangle revolves around the intertwined lives of the Kovac and Williams families and their network of friends and extended family. Nat Manning returned to her home town of Melbourne after ten years in England on the minor celebrity circuit. She created ripples and then waves in the lives of two clans already struggling under the weight of their myriad secrets. Ally is the devoted wife of builder Vince, mother of Romeo and Gigi, who is happy to have her sister Nat back. Politician Tim had an affair 15 years ago with Nat, and as a result, Nat became pregnant. Tim and his wife Christine patched up their marriage and fought hard for custody of the child, Max. Divorcee Em is having an affair with married man Vince and doctor Gabriel has a secret lust for married Ally. Vince is unexpectedly killed in a random auto accident.
Season 2
With Vince now gone, secretive man Joe Kovac, brother of Vince, returns, hoping to become a part of a family he was never allowed into. Spiros Georgiades is recruited by the party as a political adviser to Tim, and develops an attraction to Christine. Tim makes a bid for the top job of Premier, but is kicked out of the party after an honest press conference. Ally and her children, Romeo and Gigi, make a fresh start in a new house; Nat meets a young, successful man and Gabriel's new outgoing girlfriend, Sophie, looks a lot like Ally.
Season 3
Season Three will pull apart and look at just how the generations separate from one another and how the ties of family are stretched. Ally sheds some of love's illusions and begins to see life possibilities beyond her family and Gabriel. Both Romeo and Gigi need her less than she'd imagined, but in different ways, as they build their own lives. When Max moves away, Christine flirts with a parallel life at odds with all previous certainties. Gabriel and Ally finally get together as Nat reconnects with the sinister Michael Chubbievsky, a suspected drug dealer. Nat's chaos is the one constant.
