The Courier

Ezekiel Mannings, a wealthy businessman and notorious crime lord who is under house arrest in New York, seeks the elimination of Nick Murch, the only witness who can tie him to a murder. Murch is sequestered in a heavily guarded safe room in London in order to give evidence against Mannings over a video link to the United States. An unnamed female courier and former special ops soldier delivers a package to the safe room, unaware that the package contains a cyanide gas weapon intended to kill Nick. She rescues Nick from the attack and discovers that his protection detail has been compromised.
