When the intelligence service discovers a threat to the British royal family they send in an undercover agent (Rachel Skarsten) as a nanny to guard the young prince and princess, whilst being attracted to and suspicious of the prince (Dan Jeanotte). This is better than the usual Hallmark Royal films as it has some mystery attached to it to give it some plot as well as the usual romance. The British setting is reasonably well done. There is a good performance from Rachel Skarsten in the lead and a small role for Greta Scacchi as the woman having to train the undercover agent as a nanny.
