She secretly falls for Ethan, a company employee, only to discover he has been dating her sister Julia as part of a scheme to secure money for their wedding and later blackmails Cassie over a hidden secret.

As Cassie investigates, she uncovers that Ethan may actually be her stepbrother seeking to destroy the family legacy, and that Julia is likely involved in their father’s suspicious death, though there’s no proof.
