Because of a chance overheard conversation by a man in a bar telling someone else about a possible bomb threat, a very secret spy agency is given a mission to go undercover to find the person who may have the bomb. Complicating matters, it is learned this person was a former spy and has moved away to a retirement community, and because of national security, all agencies refuse to identify him or give out any information about his location or even acknowledge his existence. The choices come down to whether to alarm the entire area which may cause total panic and injury or move in as residents and find him. A suicide and a train wreck get in the way of the investigation which leads to a dramatic and tragic ending of the situation.
