加油站的燈管在雨夜閃亮，準備修燈的年輕員工阿芬心情忐忑，原來她意外懷孕。同時，少女芸芸為了擺脫母親掌控，離家出走來到站內遊蕩。準媽媽遇上問題女兒，各自對被加上的身份充滿焦慮，但這段短暫的邂逅卻意外撫慰彼此的心。

寂寞微雨夜，偶遇暗燈中，她與她的短短碰面，不是兩生花式的命運邂逅，而是闌珊疏影處的惘然相會。阿芬意外懷孕，芸芸離家遊蕩，一個在考慮要否成為母親，一個在逃避媽媽的束縛。孤獨、貧窮、感情煩惱、生活空洞⋯⋯都沉重地壓着兩顆少女心，然而在身份焦慮的重疊處，微塵相聚在窄路，她與她由陌生到互慰，憑藉的不是言語，而是像待修的燈管般時明時暗的靈光互通。未來依然未知，但在這個陰冷而有點魔幻的夜晚，她與她點亮了內心燭光。

On a rainy night, Fen encounters teenaged runaway Yunyun at the gas station she works at. Fen is unsettled by the discovery that she is with child while Yunyun is distressed by her mom's behaviour at home. Their meeting, though brief, offers them both a moment of escape.
