Lawyer Macy (Sandra Ng) is defending Robert (Eric Cheung), the boss of an advertising company who is accused of abusing his wife. They have a one-night stand and Macy becomes pregnant. Feeling conflicted, she attends a psychological counseling class for single mothers, but unexpectedly runs into her high school sweetheart Anita (Vivian Chow). Previously, Anita and 19-year-old Mike (William Chan) also had a one-night stand on their first date and unfortunately got pregnant. Romantic memories of the past come to mind, and they find that they still love each other and decide to get together again. Anita wants to live with Macy and raise a child together, but Macy doesn't dare to take responsibility for her relationship. Her friends Huihui (Joanne Ku) and Eleanor (Elena Wan) are also worried about her. At the same time, Anita suffers from unfair treatment in the company, and Huihui and Eleanor gather a group of homosexuals to protest. Macy also faces her unstable emotional attitude for the first time. Robert and Mike, as the father of the child, also want to take responsibility for this. Will Macy be brave enough to take on her responsibilities in the end? What will be the fate of these four people who break the conventional relationship between men and women?
