Summer of 69 from writer and director Jillian Bell is a funny tale about a naive high school girl who thinks knowing how to execute a particular sex activity will land her the boy of her dreams. It sounds like it’s about sex, but it’s really about growing up and making friends.

Summer of 69 is all talk about sex. Nobody actually has sex. And the talk is hilarious and ridiculous. Abby (Sam Morelos) has been in love with Max (Matt Cornett) since third grade. Now that she’s 17 and her hormones are getting her attention, she’s prone to long and funny fantasies about Max.

Abby has no friends. She gets her advice from the guy in the school mascot outfit (Fernando Carsa) who sits on the bleachers during practice and extracts cash for advice. He tells her that Max’s favorite position is 69 so she wants to figure out what that is.

Abby goes to a strip club where she sees Santa Monica (Chloe Fineman). She’s wowed by how free Santa Monica is with her body, how sexy she acts, and how confident she is.

Abby decides to hire Santa Monica to teach her about sex.

Abby makes money by live streaming herself playing a video game. She has $5000 in cash in her bedroom. But that’s all her money.

Santa Monica doesn’t normally teach teens anything, but she and the other strippers just found out their boss Betty Spaghetti (Paula Pell) is going to have to close the club because of a $20,000 debt. If she had $20,000 she could buy the club and be her own boss!

Santa Monica tells Abby she’ll teach her because Abby promises her $20,000. Abby doesn’t have that much money, but being 17 means she’ll figure it out in a day or two. Right? Yeah, right.

All that is the first act. The remainder of the movie is a sweet story about how Abby and Santa Monica become friends, how Abby grows out of her childhood fantasies and realizes some important things about herself and Max.

Santa Monica has her own subplot about her high school nemesis played by Natalie Morales.

Abby and Santa Monica both have a character arc of growth, which is what makes this movie so warm and charming.

The big finish tells what happens when Abby finally confesses she doesn’t have the money she promised. It all comes to a fitting and satisfying ending.

This seriously funny comedy is streaming on Hulu. Kudos to Jillian Bell for a great job in her first stint as a director.
