If you are fan of 'what if?" fare, this is a good one. The last ship in the US Navy sails to San Francisco Bay to see if anyone is left after a nuclear exchange providing a dark, somewhat comical surprise.
This movie plays on Turner Classic Movies on 27 Feb at 8ET/5PT. See tcm.com for the full schedule.
(If you want to know what the dark, comical surprise is, or saw this movie and forget, you can PM me so that I don't ruin it for others.)
