Her only moments of peace come when she is in her car. A chance meeting brings Anson face-to-face with Sunday once again, & she decides to hire him as her driver due to his righteous & headstrong personality. After weathering several professional & personal obstacles together, Anson & Sunday become each others confidants & begin to develop feelings for one another, but they are unaware of a dangerous situation thats hurtling towards them.
