姑娘十八一朵花The film follows successful business owner David (Ochmann), who leads a comfortable life alongside his boyfriend, Álex (Bassave), an attractive gym instructor. The latter has always wanted to become a father and often wonders which path he should follow in order to make his dream come true: adoption? A surrogate mother? Nevertheless, David refuses to discuss the subject. That is, until Blanca (Perroni), David’s sister, with whom he broke off all contact after a dark event in the past, bursts into their lives. She used to be a drug addict and, in one terrible moment of carelessness, started a fire that killed their parents, for which she was sentenced to six years in prison. But now, she is clean and has resolved to win back the only family she has: that’s why she will be willing to do whatever it takes to persuade her brother to accept her into his life again.
