'고구마'는 감옥에서 출소 후,
바닷가 근처에서 작은 점포를 운영하며 근신한다.
그러나 한 번도 만난 적 없는 옛 '상사',
빚을 떠넘기는 어머니,
친구 '마오지'가 그를 과거의 소용돌이 속으로 끌어들인다. 

제80회 베니스 국제영화제 '미래의 사자상'을 받은 리홍치 감독의 데뷔작.

Since his release from prison,
Sweet Potato has been content with running a small business
with meagre earnings by the seaside,
heedless of other people’s advice against it.
He is pulled into the whirlpool of his past when his old “boss” (whom he has never met),
his mother (who thrusts all her debts upon him),
and his buddy Maozi all re-appear into his life.
One after the other,
they regain control over his present life leaving him no hope for the future.
Only Seven can assuage his anxieties ever so slightly.
One day, at the smoggy and oppressive seaside,
Sweet Potato is finally granted a meeting with the “boss”…
