After growing up in a rural village, 21-year-old Isabella Patton is sent back to her wealthy biological family. She soon crosses paths with the charming (and much older) Oliver Bates, who begins to pursue her relentlessly, unaware that she is his promised fiancée. Meanwhile, Isabella’s cousin, Eliza—who was raised by the Pattons in her place—is desperate to turn the family against Isabella. Unfortunately for Eliza, Isabella is a hidden genius with unmatched skills in medicine and technology, easily outsmarting her at every turn. As Isabella's brilliant talents come to light, she wins over her parents and five brothers, becoming the crown jewel of the Patton family while keeping the smitten Oliver chasing after her.
