Lanny (Chuck Carrington) is about to graduate from school, and what awaits him is an infinite future. But at this juncture, Lanny's father passed away. Not only that, his father donated all his property to charity, leaving Lanny with only a mysterious little box and a short-selling company called "Covenant List" that he had never heard of, which made Lanny puzzled. Later, Lanny met a beautiful girl named Johnson (Hilarie Burton). The lively and gentle Johnson gradually attracted Lanny's attention and made him fall in love. However, Johnson did not decisively accept Lanny's feelings. Her hesitant and evasive words made Lanny firmly believe that there must be a hidden story behind it. As time went on, the secrets of the company left by his father gradually surfaced.
