The old Santa's drunk and Mandy Brooks, assistant manager of Wentworth's, an upmarket department store doesn't do Christmas. Then she's forced to play the part of Mrs Santa in the store's grotto. Trouble is Santa's replacement is a blast from her past – one she ran away from at the altar five years ago. Ditched on his wedding day, Tate Sullivan left town. Now he's back and he's got unfinished business with Mandy Brooks. He wants her back in his bed on his terms, his way. But nothing is going according to plan.
