In the year 2229, cash-starved prospector Mia Blancharde uncovers a valuable relic while digging around the swing zone, a shared forest area that lies between two cities. To the north is Freedale, a polluted militaristic metropolis on the cutting edge of high technology. To the south sits picturesque Lakeside, a quiet rural community of earth-loving purists.
A delicate accord between the two cities has allowed their peaceful coexistence, but as activists from Lakeside start taking potshots at Freedale, Mia's brother, Colonel Zavier Blancharde, calls for an attack to retaliate against them. With the swing zone fast becoming a battle zone, Mia rushes to excavate her find with the help of Coltis Lawson, an archeology enthusiast from the purist side. His knowledge and almost magical capabilities only serve to confuse her further, as she finds herself unwittingly falling for a man she's not sure she can trust.
With her opinion swaying back and forth along with the tide of the conflict, Mia comes to learn there's more at stake than she could possibly imagine. Torn between her love and her city, she struggles to uncover the mysterious truth while trying not to get trapped on the wrong side of a very dangerous line.
