這一天是刑事組長南哥退休的日子，也是服刑多年的老廖出獄的一天，昔日各自代表的身份，都隨著光陰荏苒卸下。兩人重聚後，南哥才發現老廖在監獄裡被廢了右手，此刻的老廖已不會再是一名扒手，正如同脫下制服的自己也不再是一名警察。南哥想和對自己恨之入骨的女兒和解，獲得原諒；而老廖則想找到當年喊著自己爸爸的小扒手，一解遺憾。兩位遲暮之人帶著未解心事，啟程上路，卻也意外捲入未解恩怨……。

潘志遠執導，硬派演員喜翔及蔡振南共同主演，人至耄耋，行將就木；金盆洗手，恩怨已淨，心中的罪惡能否得到希望與救贖，彌補不可挽回的親情和傷痛呢？曾以《指尖的重量》描寫誤入歧途的小扒手經歷社會殘酷的洗禮，相隔近20年後，再次以老扒手與退休警察各自的未了心願，參混著公路電影色彩，安排重新踏上江湖之路，其中的意境與況味更可相互對望。

The day Liao is discharged from prison with his maimed right hand is also the day Nan is forced into retirement. Now, Nan is no longer the head of CIB, just like Liao is no longer a pickpocket. Liao wants to find the young pickpocket who used to call him "Daddy" back in the day, while Nan badly misses his daughter, who hated him deeply and was unwilling to forgive him. These two desperate old fellows go in search of their last hope.
