After the sudden death of baby Jamison's parents, custody is awarded to both his aunt Sophie Rossi and his uncle Luke Mason. With Luke nowhere to be found, Sophie quits her prestigious job in San Francisco and moves into her sister's farmhouse in Shell Beach to care for Jamison. After six months, she still struggles to fit into her sister's capable shoes.
Then Luke Mason resurfaces without explanation and wants to be a part of Jamison's life.

As Christmas nears, Sophie and Luke's love for Jamison draws them together, causing them to rethink their plans for the future and redefine their ideas of family.
