Ridiculous nonsense.
Especially in the follow-on from Russiagate, who can honestly say that a plot this hackneyed is even remotely plausible?
The most unrealistic interiors provide a ludicrous backdrop for a bunch of actors who never look scared enough.
Even the 'ping' was disappointing.
A far more complex, realistic and terrifying plot might I suggest be set during the dying days of the American Empire featuring sociopathic Yanks with nukes, refusing to go quietly.
