When Abby and her 12-year-old daughter leave their home on Maui and set off across the United States on a road trip to Louisiana, Abby is sure that this trip is about Hannah. Abby wants Hannah to receive a blessing from Abby's grandmother and the matriarch of the family. This blessing, she is sure, will fill Hannah with confidence as she heads into the challenging years of adolescence. What Abby doesn't expect, is that in many ways, this trip is about her and her own complicated relationships between the generations of women in her family, including her estranged mother. The sweet scent of Gardenias permeates this engaging look at the intergenerational journey of women, as it also reminds us of another sweet fragrance-forgiveness.
