Madeline is very angry at her ex-husband, Nathan, since he has recently moved back to town with his new wife and daughter, Bonnie and Skye. Nathan has been very involved in his daughter Skye’s life which hurts Madeline since he left her alone to raise their daughter Abigail. Madeline has remarried and has two children with her husband Ed (Adam Scott).
Madeline is taking her daughter Chloe to Kindergarten roundup and has some trouble. Jane Chapman (Shailene Woodley) stops to help. The two women find out they are going to the same place since Jane is taking her son Ziggy to school. Jane is a single mom and new to town. Madeline decides to take Jane under her wing. She remembers what it is like to be a single mother and to be judged by the other moms. When they arrive at school, we are introduced to Celeste (Nicole Kidman) and her twin sons. Celeste appears to have an ideal life. Her husband Perry (Alexander Skarsgard) is handsome and wealthy and she has two adorable boys. But we see glimpses of their home life and see that Perry abuses Celeste.
At the end of the Kindergarten roundup, one of the girls is hurt. She has bruises on her neck. The teacher asks her to identify the person that hurt her. She points her finger at Ziggy. Jane stands up for her son to the rest of the parents and Madeline stands by her side. A battle line has been drawn between the parents before school has even started.
Throughout the episode and the series, we see different members of town being interrogated at the police station. Most of them mention Madeline and Celeste and the women at school. The viewer is unsure of what has happened. From the brief instances of conversation, the viewer can guess that someone has died and it might be a murder. Who died is not revealed. So throughout the series, the viewer is left wondering which character died and who the murderer might be. The series has seven episodes. A delicious drama and tantalizing mystery leaves the viewer guessing and wanting more.
