Natalie, the proprietor of a cupcake food truck in San Francisco, and Eric, a financial manager and divorced father, are thrown together when Eric's aunt, who was also a long-time customer of Natalie's, dies and leaves them a building that was formerly home to a famous bakery. As a result of being forced into this new relationship, they realize that selling the building will be difficult due to its designation as a historical landmark. As they work together to renovate the old bakery, romance blossoms. However, Natalie's determination to conduct business alone may bring the partnership to an end prior to the grand launch.
