There is a massive attack on the White House and despite there being heaps of highly trained secret service and the like around, it is only Mike Banning (Gerard Butler) who can save President Benjamin Asher (Aaron Eckhart) and his small son.
If you like a ridiculous action plot, here it is. One man against the terrorists. Wonderful. So wonderful, just like the wonderful action films from the eighties and nineties. Awesome.
