The person who breathes life into the far-fetched screenplay is Australian star Isla Fisher. It’s her first major leading role having been a worthy supporting player in films such as Wedding Crashers and Hot Rod. She plays Rebecca Bloomwood, a young woman living in New York who works for a gardening magazine.

To use the term from the title – Rebecca is a "shopaholic". She can’t help herself. She loves the thrill of walking past a shop window and seeing something that she simply must have. It should come as no surprise to learn that she has 12 credit cards, all of which are near their maximum limit.

When her current employer goes bust, Rebecca finds herself desperately looking for another job. Rebecca has always wanted to work at Alette Magazine, a high-profile publication released by fashion guru Alette Naylor (Thomas). She thinks she’d be perfect given her love for the industry. Sadly, there’s no current position available.

Looking to find a way in through the back door, she applies for a job at Success Savings – a finance magazine run by the same company. Rebecca thinks she can use it as a platform to something bigger.Of course, Rebecca knows nothing about finance. Her new boss, Luke Brandon (Dancy), realises that fairly quickly. He sees potential however. Rebecca starts a column called "The Girl With The Green Scarf" which becomes a smash hit with readers. She takes complicated financial issues and helps explain them using easy-to-understand metaphors.
