At a party at a French chateau, a woman referred to only as A is approached by a man known only as X who tries to convince her they met a year ago at another gathering, while another man, M, who may or may not be her husband, looms in the shadows. Alan Resnais' Last Year at Marienbad, from a screenplay by Alain Robbe-Grillet, is a hypnotic, jigsaw puzzle of a movie which achieves the incredible feat of suspending disbelief entirely in a work completely devoid of plot.
