Andover (2017) on Netflix

Plot summary

Adam Slope is a genetics professor. He nervously proposes to Dawn, a carefree glass blower and artist, and after they marry they take out life insurance policies on each other. A fire at Dawn's studio kills her. Overwhelmed by grief, Adam pulls hairs from her hairbrush and sets out to clone her in his lab, with help from his overeager graduate student Emma. The clones begin as babies and age into adults over three or four months, and the ones he raises at home and in the lab have problems that keep them from being the woman he lost. Adam grows obsessed with perfecting them, starting over whenever a clone is not the Dawn he remembers.
