The series centers around Robyn McCall, an enigmatic woman in New York City and single mother to teenage daughter Delilah with a mysterious background who uses her extensive skills to help those with nowhere else to turn, acting as a guardian angel and a defender for those who cannot defend themselves while pursuing her own redemption.
Having grown disenchanted with her work, Robyn leaves the Company to raise her teenage daughter Delilah.
Through careful undercover work, and with the assistance of her former superior William Bishop, Robyn captures two mercenaries employed by a tech mogul, who had Chance murdered to cover up his discovery of a fatal flaw in the software for his latest product, a self-driving car.
The mogul is arrested by Marcus Dante, an NYPD detective who Robyn met earlier while posing as Jewel's lawyer.
Jewel is released and Robyn decides to send an anonymous online message offering to help anyone who has "the odds against them".
