Split between the parallel realities of contemporary London and the otherworldly metropolis of Meanwhile City, Franklyn follows the tales of four characters. Jonathan Preest (Ryan Phillippe) is a masked vigilante who will not rest until he finds his nemesis, the Individual. Emilia (Eva Green) is a troubled young art student whose rebellion may turn out to be deadly. Milo (Sam Riley) is a heartbroken twentysomething yearning for the purity of first love. Peter (Bernard Hill) is a man steeped in religion, searching desperately for his missing son amongst London's homeless.
Beginning in Meanwhile City, the film moves into contemporary London as the characters' storylines intertwine for a fateful finale.
