[6] Hai Phượng is an ex-gangster who is estranged from her family after her father disowns her for having an affair with a gangster and getting involved with criminal activities.

After a lengthy chase, Hai Phượng barely loses them, but not before learning that the thugs are taking Mai to Saigon.

Hai Phượng then goes to her brother for help, but he refuses to help her due to him not getting over the fact that Hai Phượng betrayed their family to become a gangster and never came back to reconcile with them when she left the gangster life and never attended her parents funeral, where he also tells that she is a terrible mother and Mai deserves better.

[7] Previously, the film was scheduled for release in the fall of 2018, but it was delayed to early 2019 due to distribution agreements in other countries.

[17] The film was also made available on several on-demand services in the United States, including iTunes, Comcast, Amazon, Google Play Movies & TV, Vudu, Playstation, Xbox, Fandango, Charter, and DirecTV.

The site wrote: "If Jennifer Garner wants to make another action movie like Peppermint, she should take notes from Ngô Thanh Vân, a star with explosive charisma and bone-crunching Vietnamese martial arts.

Hai Phượng may be the most entertaining film of its kind since The Raid 2 made waves outside Indonesia five years ago.

"[27] In contrast, Minh Tranh of Tuổi Trẻ Online commented: "Visually impressive in terms of action, but the script of Hai Phượng is so simple that it feels rather superficial.

What made Hai Phượng become such a reckless and disillusioned person despite being born into a relatively peaceful family is never explained.
