Hamid, who has a dispute with his wife "Mehri", leaves his wife and daughter "Mahtab" and goes to a cafe. Hamid meets a dancer named Mina, who tries to trap him in a smuggling gang led by Ahmed. "Mehri" seeks revenge as a result of Hamid's indifference and under the influence of his friend "Fati". "Hamid" signs a white check at a drunken gambling game and hands it to "Mina" and "Ahmad"'s people. The next day, when the check is returned, he gets involved with "Ahmad" and his men, and they invite him to cooperate and move the smuggled diamond package from one place to another with Hamid's cooperation, while carrying the second package of "Mehri" from "Hamid". She informs Ahmed of the danger threatening her husband and informs Colonel Javad, the head of the gendarmerie. The gendarmerie pursues the smugglers and "Hamid" hands over "Ahmad" to the colonel.
