Mallory has just made a series of disastrous decisions that may destroy her career. In the aftermath, she just wants a long hike, maybe to find a geocache, and to be left alone to sort out her troubles.
Instead, she finds herself on a madcap chase through the Utah desert with an aging hippie and a dusty old treasure map as her only guides.
Chased by unknown strangers, lost in a maze of bewildering rock formations, and running out of time, can Mallory find her way out, find the mythic treasure of the Lost Frenchman, and maybe find a solution to her problems before it all catches up with her?
