The Batts family has arrived at a hotel in Los Angeles and everything is all set for Aunt Laura's wedding weekend.
Stella and Penny are going to be getting a new uncle, and a new cousin Plus, they get to be flower girls, and wear fancy dresses, and walk down the aisle throwing rose petals.
It's going to be perfect--just the way Aunt Laura has imagined it.
Just the way Stella has imagined it, too.
But sometimes a wedding doesn't happen the way anyone thinks it will--including the bride.
Things are starting to go wrong, and Stella is worried that it's all her fault.
