Seen through the eyes of 17-year-old Cassandra, who narrates the film through the writings in her journal, I CAPTURE THE CASTLE tells of an eccentric family struggling to survive in a dilapidated castle, with huge back rent debts and a father who has yet to repeat the success of a best-selling novel he wrote some twelve years before and who has not written another word since. Cassandra and her beautiful sister Rose, their bohemian step-mother Topaz, her young brother Thomas and orphaned, unpaid help Stephen live an isolated life, completely oblivious to the outside world. When their castle is inherited by two American brothers not only are they thrown into disarray at the prospect of finding means to pay their outstanding debts, but the innocent bubble in which the family has existed for so long is pierced and the sisters are awakened to feelings of love, longing and jealousy.
