A story about a
single mom with a smart son and a normal son isn't «big» enough on its own, so it sets up the whole plot about «Well, what if the smart son realized the
girl he had a
crush on was being raped by her stepfather and set up an elaborate plan to kill the stepfather?»
There's Lucas Hedges» Danny, a theater kid for whom she develops a fast
crush; academic superstar and best friend Julie (Beanie Feldstein); resident rebel and all - around D - bag Kyle (Timothée Chalamet); and cool
girl Jenna Walton (Odeya Rush), a plastic,
single - serving friend who could lend Lady Bird the kind of social capital she'll need to enter Kyle's skinny jeans.
