Meredith Rossman has made Rossman's Department store her entire life, not leaving any time for Christmas or romance. But when she is roped into donning the store's antique Mrs. Claus outfit to play Mrs. Claus at Rossman's famous Santaville, her life takes some unexpected turns. Through the help of the suit and the charming store Santa, Nick, Meredith rekindles her love of Christmas, the store, their employees and possibly even begins a new love with Nick.
