102 Dalmatians (2000)

After a spot of therapy, Cruella De Vil is released from prison a changed woman. Devoted to dogs and good causes, she is delighted that Chloe, her parole officer, has a dalmatian family and connections with a dog charity.

But the sound of Big Ben can reverse the treatment so it is only a matter of time before Ms De Vil is back to her incredibly ghastly ways, using her new-found connections with Chloe and friends.
