Zoé, a very busy nurse, relied on her mother-in-law Denise to take care of her son Léo during her night shifts. But recently, Léo had started dreading his grandmother’s visits, clinging to Zoé and hiding when Denise arrived.
When he finally revealed the reason, Zoé was shocked: Denise had used a cotton swab to collect Leo’s saliva and had been following him to do a DNA test. Her motive? Denise doubted Leo’s paternity because of his blonde hair.
Zoé angrily confronted Denise, who admitted her suspicions. Andrew, Zoé’s husband, suggested a DNA test to clarify things, but Zoé added her own condition: Andrew would also have to take a DNA test.
When the results arrived, Leo’s paternity was confirmed, but there was a problem: Andrew was not Leo’s biological father. The revelation shocked Andrew, and he distanced himself from Denise, who admitted to having had an affair a long time ago. With her insecurities exposed, Denise lost her hold on the family, while Zoé and Andrew decided to move forward and leave the past behind.
