It's 2025, and America teeters on the brink of fascism. Natalie Morrow watches in alarm as her son Augie and daughter-in-law Nicole turn a blind eye to the encroaching signs of tyranny, clinging to a dangerous hope that things will somehow improve. Natalie can't do this; she refuses to gamble with the safety of her grandchildren. Instead, she makes an unfathomable decision: to flee to Canada and take Liam and Charli with her. Embarking on this fraught mission, she's fully aware of its ramifications but determined to shield her cherished grandtwins from the fate she believes awaits them in a country she still loves but no longer recognizes. Meanwhile, her other son, Finn, has been MIA for months. A radio podcaster, he's gone deep undercover to infiltrate a compound of radical white nationalists, risking everything to expose their violent agenda. As mother and sons' paths converge and the stakes escalate, Allegiance becomes a pulse-pounding tale of resistance, sacrifice, and the enduring power of family. Will Natalie and her grandchildren find sanctuary beyond America's borders, away from the new regime, or will the fight for survival lead them deeper into the heart of the ongoing storm? And who, in the end, merits our ultimate loyalty?
