纪录片以中越边境东兴-芒街为原点，定格越南边民吴氏翠的东兴商铺日常与中国东兴商家邓姐的跨境采购足迹，勾勒出边境线上跨越国界的生存故事。她们的故事，是边境线上无数边民的缩影。纪录片以三段时间切片，记录“社群”“合作”与“疫情”的命题。

The Border takes the Sino-Vietnamese border towns of Dongxing and Mong Cai as its focal point, immortalizing the daily rhythms of Vietnamese resident Wu Shicui's Dongxing storefront and Chinese merchant Deng's cross-border sourcing journeys, sketching a borderland survival narrative that transcends national divisions. Their stories echo the experiences of countless border inhabitants. Structured through three temporal vignettes, the documentary engages with themes of "community," "collaboration," and "pandemic resilience."
