Mae'n Nadolig. Mae'r byd y tu allan yn ysgytwol gyda llawenydd a llawenydd yr ŵyl. Yn y cyfamser mae Jan, mam sengl ifanc sy'n brwydro i gael dau ben llinyn ynghyd, yn credu ei bod wedi methu ei merch.

Convinced that she is better off without her, it is not until Jan encounters an older woman at a train platform with a similar story, that she begins to reconsider her decision.
