When former deep-black operative Aaron Decker helped Matthew Redd escape both a blizzard and a team of killers, Redd promised to return the favor if he was ever needed. Now, that favor is being cashed in.

Though he's been living quietly with his family in Michigan since his 'death' ended his military career and former life twenty years ago, widower Aaron Decker wakes one night to a home invasion that is clearly not random. Someone has finally found him. After narrowly escaping a Russian mafia hit team, he takes no chances with his children's safety and relocates them to a remote Upper Peninsula cabin where he awaits the arrival of his old ally and former Marine Raider, Matthew Redd.

When Redd arrives, he's eager to make good on his promise to repay his debt. Redd and Decker work together under constant threat to transport Decker's kids to Redd's ranch in Montana. Then Redd convinces Aaron to leave the kids in his wife Emily's care, camping at a remote site in Yellowstone National Park under the watchful eye of FBI director Gavin Kline. Meanwhile, the two men take off to investigate the source of the mysterious leak feeding Decker's whereabouts to the Russian mob.

While Redd and Decker cross the country, following leads that seem to point to a traitor in Decker's former deep-black ops unit from the early years of the War on Terror, Emily and the kids find they're not as safe in Yellowstone as they hoped. When they learn of the danger, Redd and Decker can only hope that they're not too late as they race to protect their families.
