LONDON. THE STANHOPE HOTEL, PARK LANE. 16.00 A normal afternoon.

THE MANAGER
Newly engaged Elena Serenko has just made the life-changing decision to quit her job and start a new life in Australia.

THE GUESTS
Upstairs, a young woman waits for her lover; a visiting family prepare for an evening out; and a sick man contemplates his own mortality.

THE ASSASSIN
High up amongst the penthouse suites, a skilled and dangerous killer is hunting a quarry who’s eluded him for far too long.

THE SIEGE
What none of them know is that a group of ruthless gunmen are about to burst into the Stanhope, shooting indiscriminately, and seizing hostages.

As darkness falls and the gunmen become increasingly violent, only one thing matters. Who will survive?
