本片改编自理查德·麦奎尔的同名热门漫画，聚焦一间房子，和多年来房子里来来去去的许许多多人，从过去到遥远的未来，在固定的空间中凝视时间的片段和流逝。由Playtone和ImageMovers公司制作。

Events in India's history — from the Emergency and the famous Cricket World Cup win to the Punjab riots — unfold from the perspective of an innocent Sikh man Laal Singh Chaddha, a person with a low IQ but high optimism. Laal is able to achieve everything under the sun but his childhood love continues to elude him.

A man with a low IQ has accomplished great things in his life and been present during significant historic events—in each case, far exceeding what anyone imagined he could do. But despite all he has achieved, his one true love eludes him.
