This Barbie belongs at the top of the food chain.
After a disastrous party where she somehow kills a bratz doll who, by the way spilt beer on her dress, things seem to be going downhill. Her fame is dwindling until she's just a nobody, just another troll doll.
So with the aid of her lesbian partner - or, as she refers to her, her fucking partner - and Ken, who she fucking hates, by the way, she might just find her way back to the top of the food chain where she belongs.
