Assassin

Basic setup

The film takes place in a slightly futuristic / sci‑fi setting where a private military or black‑ops organisation develops a microchip technology enabling the conscious mind of one agent to inhabit (or transfer into) the body of someone else. Wikipedia+2Movie Insider+2
Bruce Willis plays Valmora, the high‑level figure in charge of this operation. Wikipedia+2IMDb+2
Mbatha plays Alexa, the wife of an agent, who is drawn into this covert world when tragedy strikes. Keith & the Movies+1

Story outline

1. Alexa’s husband, Sebastian (played by Mustafa Shakir), is involved in a secret mission using this mind‑transfer technology. At some point he ends up in a coma (or critically injured) as a result of the mission going wrong. Keith & the Movies
2. Alexa investigates what happened and discovers that Sebastian wasn’t just a soldier but part of an experimental programme led by Valmora’s organisation. The technology allows one body to serve as a “drone” – a vessel inhabited by someone else’s mind for covert operations. Keith & the Movies+2Wikipedia+2
3. The villainous element: An individual named Adrian (played by Dominic Purcell) has stolen or gained control of a piece of the technology, posing a massive threat. Alexa is recruited by Valmora to step in, inhabit other bodies, carry out assassinations or missions to recover the tech and save her husband. Wikipedia+1
4. Alexa, now thrust into the role of operative, must use the body‑transfer tech, assume other identities/bodies, follow the trail to Adrian, and bring him to justice — all while time is ticking and her husband remains in peril. The movie focuses on her moral conflict, the blurred identity lines, and the organisational secrecy. Keith & the Movies+1
5. In the climax, the lines between who is controlling what body, who is really the “agent” and who is the “drone” become blurred. Alexa confronts Adrian, uses the tech herself, and makes choices about sacrifice, identity, and justice. The fate of Sebastian and the future of the transfer‑technology hang in the balance. (This summary doesn’t reveal every twist, but gives the broad arc.)

Themes & Notes

• Identity & body‑hopping: The concept of transferring a mind into another body raises questions of agency, ethics, and what it really means to be “you”.
• Sacrifice & loyalty: Alexa loves her husband and is willing to risk everything, including her own body and self, to rescue him.
• Science‐fiction meets action: The tech is futuristic (microchip enabling body inhabitation), but used for typical covert military/assassin missions.
• Production significance: This film marks one of Bruce Willis’s final film appearances before his retirement from acting. Wikipedia+1

My quick verdict

While the premise is intriguing, many reviewers felt the execution was weak — the action lacked energy, the characters were under‑developed, and the story had holes. Keith & the Movies+1 If you are a fan of Willis or of sci‑fi assassin thrillers, you might find it interesting; if you expect tight plotting or major production polish, maybe lower your expectations.
