The story is told in a heavily serialized manner. It revolves around the lives of Wali and Faarah, who were forced to commit to each other for the cause of reuniting their family, which had fallen apart long ago because of Agha Jaan's eldest son Behroze, when he called off his long engagement to marry his late love interest.

Diyar-e-Dil features an ensemble cast with Abid Ali
