在中国传统文化中， 当微风吹起风铃声响，代表有先人或魂魄到访。这是一个信号，告诉在世的人「我」回来了，亦是再次提醒他们至亲至爱已经永隔的事实。 《无声风铃》是一部关于放手的电影，它紧凑地展现了东西方在生活哲学、看待死亡与来世上的区别，同时也模糊了爱情与种族的界线、呈现不同文化的融合与一致。本片是香港导演洪荣杰的第一部剧情长片。

The hospital calls Fareed; his wife's situation is critical; the cancer has reached its terminal stage. Pensioner Roli comes to his help and takes him to see his wife who passes away shortly after. Her funeral falls under the jurisdiction of Amrikon council. Fareed wants to see his wife buried in accordance with Muslim rites. Roli is keen to help Fareed and his daughters but problems quickly arise: the graves in the local cemetery have not been aligned to face Mecca; the council is unable to carry out the burial within 24 hours after death. Councillor Thomas Künzli assures everyone that they'll organise things for the following week. Unimpressed by the council's tactical heal-dragging, Roli offers a more creative idea: a family plot would allow for the body to be buried diagonally - facing Mecca. But even family graves are exhumed after 25 years and allocated anew. For Muslims this disturbance of peace is an absolute taboo.
