　　Set and filmed in Liverpool, This City is Ours is the story of Michael, a man who for all of his adult life has been involved in organised crime, working for his friend and the gang leader Ronnie. When Ronnie begins to hint at retirement, Michael too begins to imagine another life. Because, for the first time in his life, Michael is in love. For the first time in his life, he sees beyond the day-to-day, he sees a future: something to win and something to lose - Diana.
　　This City is Ours is the story of Michael and Diana's love affair, set against the disintegration of Michael’s crime gang. For years, together with Ronnie, Michael has successfully been bringing cocaine into the City and beyond, directly from Columbia; but when a shipment goes missing, he knows their Kingdom is under attack.
　　This City is Ours explores what happens when Ronnie’s son Jamie decides he wants to inherit their kingdom and that there is no longer a place for Michael at the table. Both Michael and Jamie have bold ideas to modernise the gang and they will battle for control of it. But Michael’s biggest battle will be to save the woman he loves and the child he has always wanted.
　　This is a story about family, and love destroyed and corrupted by ambition, pride and greed. It’s a story about power: what we will do to secure and keep it.
