As the typhoon raged on, the group of friends huddled together in their mansion on the remote island. Tensions ran high as they were forced to spend two days cooped up in the house, with nowhere to go and no way to leave. Each had their own personality, their own secrets, and their own motives. Mobin was the first to go. He was found dead in his locked bedroom, with no signs of struggle. Ali was the next, followed by Amin. Each death was more strange than the last. It was impossible to believe that anyone could have killed them, as there was no evidence of outside entry and no apparent cause of death. Then the letter arrived. A single sheet of paper, with a message scrawled in spidery handwriting. "I am Beatrice, the witch of this island. I will kill you all before the typhoon passes." Panic set in as the group realized that they were not alone on the island, and that they were being hunted by someone they couldn't see or touch. Arian and Anahita were next, both found dead in their separate rooms with no explanation. Saber, MohammadMehdi, MohammadHossein, and Amir remained, each wondering who among them was the murderer. With no way to escape, they were forced to rely on each other, even as they suspected one another of being the killer. One by one, they fell, until only one was left standing. The last survivor claimed to be Beatrice, to have been the one pulling the strings all along. But there was no way to know for sure, and as the seagulls cried out above, none were left alive. The mystery remained unsolved, leaving behind only questions and speculation.

The storm raged on as the group of friends sat in their mansion on the isolated island. Mobin, the Arab, suggested playing a game of cards to pass the time until the typhoon passed. The group agreed, and they spent hours playing and laughing. But then, as the night drew on, Mobin disappeared. They searched the house, but he was nowhere to be found. They assumed he had just gone to bed early and shrugged it off. The next morning, Ali was the first to turn up dead. The group was stunned. He had been found in his locked room, with no apparent cause of death. They were trapped on the island with a murderer, and they had to find out who it was before it was too late. The days passed, and they lost Amin, Arian, and Anahita one by one. Each death was more perplexing than the last. The killer seemed to be getting bolder, taunting them with their locked room murders. Saber was the only one with an alibi during the time of the murders, but he wasn't safe for long. He was found dead in his room soon after. MohammadMehdi, MohammadHossein, and Amir remained, each wondering who among them was the culprit. With no way to leave the island and no help in sight, they were forced to band together and solve the mystery themselves. But with each death, they became more distrustful of each other. The only thing they knew for sure was that the killer had to be among them. As the storm began to let up, they realized that they were running out of time. They frantically searched for clues but found nothing. When morning came, they discovered that the last remaining person, Amir, had also been murdered. The killer's identity remained a mystery, leaving the group to wonder what kind of monster had been among them. As the seagulls cried overhead, none were left alive to tell the tale.

The group of friends arrived at the isolated island mansion, eager to relax and enjoy a weekend away from the hustle and bustle of the city. They spent their first day drinking, playing games, and catching up on old times. But as the storm rolled in, things began to take a dark turn. The next morning, they discovered that Mobin was missing. They assumed he had gone out for a walk despite the storm but were surprised when he didn't return. Then, they found Ali's body in a locked room, with no sign of how he died. The group realized that they were stranded on the island with a murderer. As days passed and more members of the group turned up dead, the remaining friends grew increasingly paranoid and suspicious of each other. Amin, Arian, and Anahita were all discovered in locked rooms, with seemingly impossible methods of death. Saber was the next to die, followed by MohammadMehdi, MohammadHossein, and Amir. As they searched for clues and tried to solve the growing pile of murders, it became clear that the killer was one of them. The problem was that, with no way off the island and no help in sight, they had no idea who it could be. The perfect examination of corpses was not available, leaving the possibility that even the victims could have been the culprit. With the storm subsiding, the friends were out of time. They had no idea who the killer was, and they knew that anyone, even themselves, had the potential to be guilty. When the seagulls cried out overhead, none were left alive to tell the tale. The mystery would forever remain unsolved, a haunting reminder of the deadly toll the storm had taken.
