"Monogamy isn't realistic. Monogamy isn't realistic," a nine-year-old Amy Schumer methodically repeats in the opening of the trailer for her upcoming film Trainwreck.

Flash forward 23 years to Schumer's adult life, which, as the title of the film perfectly illustrates, is a bit of a hot mess thanks to her flurry of one-night stands. "I'm just a modern chick who does what she wants. Last week, it was this guy," Schumer states before insisting her life is great, "Before you judge, you should know, I'm doing fine. My friends are awesome, my apartment's sick and I have a great job at a men's magazine." 

Of course, the journalist's chaotic life receives a shake-up after the subject of her latest story (Bill Hader) becomes a potential love interest, much to the surprise and shock of Schumer.

Hilarity then ensues as the comedian attempts to navigate the difficult waters of dating while remaining completely perplexed as to why Hader is still interested after they have sex.

"He's obviously like sick or something," co-star Vanessa Bayer tells her pal. 

Directed by Judd Apatow, Trainwreck marks Schumer's debut starring role (she also wrote the script) and, as Time points out, it also marks the first time Apatow has directed a movie he didn't write.

The forthcoming summer comedy also stars Brie Larson and Tilda Swinton and "is loosely based off her [Schumer's] life."  

"A lot of the names are real, and there's a lot of us reenacting moments from her life," Larson, who plays Amy's sister in the film recently told Time. "I had to reenact a bunch of old photos she has with her sister, like bad vacation photos with disposable cameras."

Trainwreck hits theaters July 17, 2015.
