Who is the handsome cowboy who comes into small town Marietta's chocolate shop every week to buy a box of chocolates? More importantly...who is he buying the chocolates for? These are the questions sales clerk Rosie Linn asks herself as she waits for her sadly neglected childhood home to sell so she can pursue an exciting new career in L.A.Rosie finds out the answers the day rugged ranch hand Brant Willingham introduces himself and asks for her help in managing the care of his younger sister. Brant's mother has recently died, leaving him the sole guardian of eighteen-year-old Sara Maria–who has been a puzzle to Brant ever since she began exhibiting signs of autism at age two.Rosie and Brant come up with a plan. She'll help with his sister if he handles repairs and a new paint job for her old house. It seems the perfect solution, but a new dilemma is created when the couple start spending time together. Brant discovers he doesn't want Rosie to sell and leave, and Rosie fears she will have to choose between love and her dreams.
