Two-part TV adaptation of Dickens' novel. The Dorrit family have spent years in a debtors' prison due to the financial mess in which father William (Alec Guinness) managed to land himself as a youth. Youngest daughter Amy (known as Little Dorrit) finds work with the wealthy Mrs Clenham but knows that her father will, in all probability, spend the remainder of his life in gaol. However, when Arthur Clenham (Derek Jacobi), recently returned from abroad, comes to suspect that his late father was in part responsible for the Dorrits' plight, he becomes determined to make amends. But as he continues to delve into the mysteries of the Dorrits' and his parents' shared past, he is unaware that his own mother's house has been placed in peril by the arrival of a sinister stranger.
