Dubbed YouTube’s Holy Trinity, Internet sensations Grace Helbig, Mamrie Hart, and Hannah Hart return to the big screen in Dirty 30. As the new trailer shows, the film features one epic birthday party that gets even more bonkers as the night goes on.

The story follows three lifelong friends who are all in a bit of rut. Kate (Mamrie Hart) is faced with a tolerable job and struggling dating life, Evie (Helbig) suffers from the in-laws from hell, and Charlie (Hannah Hart) can’t seem to get her act together. Now turning 30, Kate allows her friends to throw her a night she’ll never forget that becomes a wild and crazy high school reunion.

Andrew Bush directs Dirty 30, which reunites the trio after 2014’s Camp Takota. Matt Dellapina, Anna Akana, Andy Ridings, Kelen Coleman, Flula Borg, and Katherine Hughes help round out the cast.

Dirty 30 drops into select theaters and on Digital HD Sep. 23. Watch the trailer above.
