On championship night, chief engineer Ella Walker arrives to celebrate with her fiancé, Lucas, only to find herself erased from the team's tribute and pressured to surrender her shares and source code. She returns her engagement ring and reclaims her cars, patents, and licenses. Lucas, his father Richard, and replacement director Sera insist she is expendable. But a 30-day transition, seven-day cloud shutdown, and disastrous livestream test expose the truth. Ella rebuilds with loyal mechanics as the Miller team faces fraud, financial ruin, and suspended credentials. Lucas finally discovers she financed their success—even their headquarters. Can he win her back?
