It was supposed to be a fun weekend for the group of friends who had gathered at the old mansion on the private island. But the typhoon had arrived early, trapping them there for two days. As they sat down for dinner on the second night, a letter with the wax seal of a one-winged eagle appeared on the table. It was from someone calling themselves Beatrice, a witch claiming she was going to kill them all before the typhoon passed. At first, they all laughed it off, thinking it was a harmless prank. But then the deaths began. The first to die was Mobin, found in his locked room with a large knife plunged into his chest. Ali was next, found hanging by his own belt in the bathroom, also in a locked room. As fear and suspicion grew, Amin became paranoid, thinking the killer was after him specifically. His fears were not unfounded as he was found dead in his own room, poisoned. As the body count continued to rise, the group became more and more frantic. Arian and Anahita were both found in one of the smaller bedrooms, their bodies twisted in unnatural positions, and Saber's body was discovered in the basement, his head bashed in with a nearby rock. MohammadMehdi's death was particularly strange - he was found in the kitchen, beaten to death, but the kitchen was locked from the inside. The remaining three - MohammadHossein, Amir, and the suspected witch - were all on edge, each thinking the other was the killer. MohammadHossein was found lying on the floor of the living room, his head caved in. Amir was found in the library, a book shoved down his throat. As the wind finally died down and the morning sun began to rise, there were no survivors left on the island. All that was left was the one-winged eagle wax seal and the mystery of who Beatrice really was - or if they had been among the group all along. When the seagulls cried, none were left alive.
