After a year apart, all Ella wants is the Last Laugh when she see her ex-boyfriend again. Don't get her wrong, she's over the cheating a-hole but everyone knows that in the game of exes coming together, there's always a clear winner and clear loser and damn if she will be the latter one more time. So with the help of her ex's cousin Carter a.k.a. The Grumpy Douche (and not because she's blackmailing him or anything,) she'll get her Last Laugh to be finally free to move on with her life.
