In the autumn of 1810, the French forces of Marshal Masséna are invading Portugal and are temporarily halted by the Anglo-Portuguese army under Viscount Wellington at the Battle of Bussaco. As a bitter winter approaches, Wellington withdraws his troops towards the fortifications he has prepared in secret at the Lines of Torres Vedras. Using a scorched earth defence, he forces the inhabitants to evacuate the land in front of the Lines and destroys all supplies which could be useful to the French. The film illustrates these dramatic events by a series of vignettes which show the effects on combatants, both regular soldiers and guerrillas, and on the civilian population.
Jaime N. Christley of Slant Magazine wrote "Dull but never dreary, Lines of Wellington was one of the projects in Raúl Ruiz's pipeline before he passed away last year".[6]
According to Xan Brooks of The Guardian "This epic historical pageant 'conceived by' the late director Raoul Ruiz won't win the top prize in Venice, but it's full of life"[7]
