After a warning visit from another uncle, Carina and her boyfriend, Navy SEAL Jay Wellman, begin an urgent search to discover the key's purpose before their enemies intercede. Following cryptic notes left by Carina's father, they go in search of the lock the key will open-but every step they take grows more perilous because there are others who will do anything to find the hidden location first. With their lives and shared future on the line, Carina and Jay race against time to unravel the threat and the promise this one simple family key holds.
