Lao Si and Wang Faye meet at work on Christmas day. Lao Si was a seaman. He lost his son after he was imprisoned for manslaughter. Wang Fay is a young person whose obsession with music is not accepted by his father. Through chatting, they take comfort from the words of each other.聖誕節那天，釋囚老四和少年王菲同在公園為安全套公司派發贈品，以賺取微薄收入。老四以前是船員，因誤殺同工而被判入獄，從此與兒子失散；王菲是一個熱愛音樂的年輕人，但他的父親視之為不務正業，因此他經常有家不歸。一個希望尋回兒子，一個渴望父親認同，對二人來說，對方可能是最了解自己的傾訴對象。
