In Your Dreams (2013)

A live-action adventure series that tells the story of non-identical twins Samantha and Ben Hazelton, who find themselves uprooted from their conventional life in suburban Australia and heading to a four-month stay with the von Hasenburg family in Germany. Upon arriving in Germany, the twins soon discover that the von Hasenburgs are no everyday people--they are the descendants of a long line of aristocrats who own and inhabit the Schoneburg Castle. Alas, time has not been kind to the von Hasenburgs, and over the years, the family fortune has dwindled to almost nothing. Now Sam and Ben must help them save the castle and turn their fortunes around before bankruptcy descends and centuries of von Hassenburg entitlement come to an end.
