A woman falls "head over heels" for a guy after accidentally spilling a vial of her new fragrance, that also might happen to be a love potion.

Shay is trying to succeed as a perfumer, and her niche is creating individual perfumes for each person. Her first store failed, and now she works from a small storage space at a storage company while also doing side gigs for a catering company. She is also attempting to recreate an antique perfume often referred to as a love potion. When she accidentally spills one of her attempts on Austin, who works for the perfume company that took over Shay's store location, and he falls madly in love with her, she believes it's the perfume that has affected him.
