The statistics show that in Thailand, 12 people commit suicide each day, or 1 person every 2 hours, and the trend is increasing. On a casual Sunday morning at The Common Sense, a mysterious woman appeared on the rooftop of the building and is likely to jump down from there. On the roof, there is only her, and the door is locked so no one can interfere with her decision. No one in the condominium knows who she is, where she is from, and most importantly, no one knows when she will jump down. All hope is in the hand (phones) of the condominium residents' group chat. They are debating on how the households can help her. Some people don't know what to do so they go live on social media. While waiting for the residents to come to an agreement, Men, a young IT boy, and Jam, residential assistance, secretly came together to find a way to stop this mysterious girl from committing suicide. Because of morality? No, that's a secondary matter! It is because if she really jumps down, it will destroy not only her life but also hundreds of lives in this condominium including Men and Jam too!
