He Who Dares: Downing Street Siege (2014)

Plot

Christopher Lowe faces the consequences of his actions when he’s called to 10 Downing Street for a dishonorable discharge from the SAS. His infraction? Disobeying a direct order, even though his defiance saved the Prime Minister's only daughter from a dangerous situation. As tensions rise, the anti-hijacking counter-terrorism team embarks on a gripping mission to thwart a new threat, blending personal stakes with high-octane thrills. Loyalties are tested, and the line between duty and morality blurs in this intense sequel to Paul Tanter's original thriller, "He Who Dares."
