General Caleb Cole faces a desperate battle at The Frontier; depleted rations, wounded. He awakens an ability to travel between ancient and modern worlds. He meets Ivy Jacobs. With help from Evie (apothecary) and Ivy, he learns modern medicine and supplies. He begins a dual life: earning money to aid his ancient camp. Bound by the rule of only carrying inanimate objects, Caleb purchases modern supplies (rations, medicine, gear, weapons, night-vision) to resolve crises.
