Tilo runs a spice store in San Francisco and has a magical gift of seeing into her customers' lives and desires. She gives them different spices to help them get what they want. In order for the magic to work, Tilo must obey the rules set out for a 'mistress of spices' - never leave the store, never touch another human, and love only the spices. When Doug - a handsome, enigmatic American with a secret past - enters her store, Tilo's own desires are stirred for the first time and as she becomes closer to Doug, the spices she has given her other customers begin to misbehave. The more Tilo falls in love and defies the rules, the worse the lives of her customers become. Tilo must decide. Will she choose forbidden love for an American over devotion to her spices and her traditions?
