Lu Feng, a former top security consultant who was framed and retired, took his cute three-year-old baby to a foreign country to find his family. After being tricked at the airport, he was forced to work as a "dirty worker" in a remote bookstore, using the incomplete jade beads to track down the truth about his grandfather's first love. Faced with provocations from hooligans and parenting problems, he used special tactics to reduce the dimensionality of his children and counterattack from a low-income black worker to an urban legend. When the family secrets are completely revealed, the whole world begs this hardcore dad to seek justice.
