Feeling tired of life on the road, Lily is quitting touring in favour of a quieter life, and to realise another dream - to open a vintage shop. The series begins backstage at The O2 Arena on the last night of Lily's tour as she prepares to begin a new chapter in her life. Along with her half-sister Sarah (a total business novice) Lily plans on making couture and vintage pieces available to those who may not be able to afford such luxury items in an innovative clothes store where customers can hire or buy one-off designer garments. They set out transforming Lily's office into the base for their business. But all they have is the name - Lucy in Disguise - and an idea.

The girls hunt for their perfect shop location and pitch for a bank loan while Lily moves house and announces she's pregnant. It's now May and the girls are due to open their shop in September, but they're still without premises, and Lily has already invested a substantial amount of her own money into the business. While Lily is pulled back into the showbiz limelight for the Ivor Novello song writing awards, where she is a triple winner, Sarah and Jess trawl the streets of London to find the perfect location for their vintage store.

In the final programme Lily and Sarah face the last few hurdles before opening the shop with a glittering launch night. But the year ends in devastation for Lily.
