My mother is a psychologist and my daughter is a rebellious student. My mother can't stand her daughter's rock music and adolescence. My daughter can't stand her new boyfriend or her self-discipline. After eating cookies from the boss in a Chinese restaurant, the mother and daughter found themselves changing identities the next day. During this period when their identities were changed, mother and daughter began to examine each other's lives, thus gaining new identities for each other. However, my mother is getting married soon, so they must meet.
