Determined to find out who has been sabotaging his business operations, Richard Sobrantes, an electronics industry tycoon, attends a secret meeting. His quest for information ends in his murder.
The day after the funeral, Sobrantes' daughter, Lauren, narrowly escapes an attempt on her life. She flees California, takes an assumed name, and settles into a peaceful life in London. But after two calm years, Lauren is attacked again. Fearing she's been found, she returns to La Lumbre, California, determined to learn the truth about her father's death.
At the family estate in the mountains above Silicon Valley, Lauren meets the new caretaker, a former US Navy SEAL and crack sniper, Sam Gallagher. Immediately, sparks fly between Lauren and Sam, and the two quickly fall for each other.
As Lauren digs into the past, people from her previous life return harboring secrets and malicious intent. Despite her passionate relationship with Sam, lingering suspicions and a mounting trail of evidence leave Lauren unable to trust anyone around her. As the pieces of the deadly mystery fall into place, Lauren learns that her father's murderers will stop at nothing to keep her quiet.
