Hotel manager Elena Monroe shares an unexpected one-night stand with wealthy tycoon Roman Montgomery. By sheer coincidence, she is picked to replace the real Reed heiress who is in jail. Under the fake name Ava, she signs a $5 million contract to marry into the Montgomery family. After marriage, she deals with her pestering ex-boyfriend and the jealousy of Roman’s childhood sweetheart Amber, while constantly fearing her secret identity will be exposed. Gradually, she falls for cold yet tender Roman amid their contractual marriage. When her fake identity is publicly uncovered, a DNA test shocks everyone: Elena is the genuine Reed heir, and the imprisoned Ava is an imposter. In the end, Elena reunites with her blood family and builds a sincere lifelong love with Roman.
