《你本该做的事》是一部爆笑、另类、却又不失和谐的家庭情景喜剧，出自露西亚·凯斯金独特的喜剧思维。琪（露西亚饰）自认是个“居家小妹”。她过着简朴的生活；吃薯片、拍些奇奇怪怪的Vlog、看情景喜剧，坦白说，20年来她就只做这些。然而，当她无比依赖的父母意外离世时，琪突然被迫独自谋生。琪将继承这栋房子，条件是她必须完成父母留下的“你本该做的事”清单（从“养只狗”到“找份工作”）。

　　Barbie Hallem is a bored rich girl, who drinks too much, parties too much and flirts outrageously with any man she meets. And there's no reason to think she stops at flirting, even though she has a boyfriend. But her boyfriend is a drip. He won't punch out a guy when he sees her kissing him. The dullard even tries to take her home when she gets drunk at a party. What she wants to do is go up to the mountains and stay at the cabin her uncle left to her. The boyfriend tries to tag along, but she manages to abandon him at the side of the road. Before the night is over, she'll wish desperately she had just gone home.
