Qiang Zi, a simple and honest construction worker, gets to know a netizen who calls herself Qian Qian on social media. Moved by her gentle words, he gradually falls into an online romance. Pan Zi, his fellow worker and good brother, spots suspicious points in it and repeatedly reminds Qiang Zi to guard against online scams, but Qiang Zi, immersed in his online romance, pays no attention and transfers money to her one after another under her inducement. In the end, Pan Zi unites with fellow worker Xiao Bai to see through the scam together, assisting in subduing Guang Tou Hui who disguised himself as Qian Qian to carry out fraud. Only then does Qiang Zi completely wake up and realize the truth of online dating fraud.
