The movie opens with a chaotic car chase through Florence, Italy, narrated by a man known only as One (Ryan Reynolds). He’s a billionaire tech mogul who has faked his own death to disappear from the world and create a secret team of operatives — each member known only by a number. Their goal? Eradicate the worst criminals on Earth — without politics, law, or rules slowing them down.

Their motto:

“No names. No pasts. No regrets.”

The Team:

1. One – The billionaire leader (Ryan Reynolds), a tech genius and strategist.
2. Two – CIA spy and weapons specialist (Mélanie Laurent).
3. Three – Former hitman and muscle (Manuel Garcia-Rulfo).
4. Four – Parkour expert and thief (Ben Hardy).
5. Five – Doctor and trauma specialist (Adria Arjona).
6. Six – Driver (Dave Franco), killed in the opening chase.
7. Seven – Sniper and military man (Corey Hawkins), recruited after Six’s death.

Flashbacks & Purpos

After Six dies, One recruits Seven, a principled U.S. Marine who disobeyed orders to save civilians in Afghanistan. Through flashbacks, we learn each member’s past:

• One faked his death after witnessing atrocities during a humanitarian mission in Turgistan.
• Two was a top CIA agent.
• Three is a father who left his family behind to join the team.
• Four is a high-speed thief and adrenaline junkie.
• Five was a trauma surgeon haunted by the people she couldn’t save.
• Six (the late driver) loved racing and took risks for fun.

Together, they are “ghosts” — operating without identity, connections, or government interference.

The Mission: Overthrow a Dictato

Their first big mission: Take down Rovach Alimov, the brutal dictator of Turgistan, a fictional country in Central Asia. Rovach has used chemical weapons on his own people, tortures dissenters, and maintains power through terror and propaganda.

One’s plan: Replace Rovach with his peaceful, exiled brother Murat Alimov, who believes in democracy and freedom.

Step 1: Destroy Rovach’s Power Structure

The team launches coordinated strikes:

1. Kill Rovach’s top enforcers in Las Vegas, Hong Kong, and the Middle East.
2. Hack and empty Rovach’s offshore bank accounts, cutting off his funding.
3. Create chaos within his regime by staging attacks and planting misinformation.

Step 2: Rescue Murat

The team infiltrates a skyscraper in Hong Kong where Murat is being held under luxury house arrest. They execute a wild extraction involving parkour stunts, explosions, magnet bombs, and helicopter escapes.

After rescuing Murat, they convince him to return to Turgistan and claim his right to lead.

Step 3: Final Battle on the Yacht

Rovach flees to a luxury yacht in the Adriatic Sea, thinking he’s safe. The team tracks him and launches a full-on assault on the ship.

• Four (the parkour expert) disables the communications.
• Seven provides sniper support.
• One and Three fight through the guards.
• Five keeps Murat safe.

They take over the yacht and livestream Rovach’s crimes to the people of Turgistan. Seeing the truth, the citizens rise up in revolution.

Rovach is captured and dropped off into a refugee camp, where his own people confront him. Murat returns home and takes power peacefully.

Ending: A New Beginning

The mission is a success. Rovach is gone. Turgistan is free.

The team stays off the grid, ready to take on the next evil. Though they are ghosts, they’ve found meaning in their work, and even One begins to open up emotionally, hinting that the past may not define them forever.

15 years ago, CIA operatives Matt and Emily are on a mission to steal a powerful device—the Industrial Control Systems (ICS) Key—from a terrorist. During the mission, Emily discovers she’s pregnant, and they narrowly escape after a brutal mid-air ambush and plane crash. Believing their deaths make their mission irreversible, they fake their deaths and vanish into civilian life

• A video of Emily using spy moves in public goes viral.
• Their former handler, Chuck, confronts them.
• Mercenaries begin hunting them for the ICS Key Matt secretly kept

Chuck and the terrorist organization Volka want control of the ICS Key—capable of hacking any electronic system. Emily and Matt are forced to:

1. Reveal spy past to their kids during a harrowing rescue.
2. Go on the run, evading pursuers across major cities, including London and England

The family travels to England to retrieve the hidden ICS Key from Emily’s estranged mother, Ginny (Glenn Close).

High-speed action ensues around the Thames Barrier, Tate Modern, and power stations.

Matt and Emily fight to rescue their children and secure the ICS Key.

They arrange to neutralize Chuck on a boat amid the closing Thames Barrier.

Chuck disappears—his fate uncertain—leaving room for more to come
