Danielle purchases a beautiful ring. The shopkeeper informs her the ring grants its wearer the ability to transform into any animal.

Unbelieving, Danielle places the ring on her finger and utters the spell. To her amazement, the ring's powers are real and Danielle is transformed into a cat. At first Danielle is enamored with her new ability. However, she soon finds herself addicted to the nightly change.

Aided by her friends, Danielle seeks to remove the ring and break free of its hold. But, she finds it stuck on her finger and the cost of removing it may be exorbitantly high.
