Sure, Melonie Diaz is a certified indie film star… But her latest project could put her on the Oscar track.

The Weinstein Co. has released the trailer for the 29-year-old Puerto Rican actress’ latest film Fruitvale Station.

Starring Michael B. Jordan, the film tells the story of Oscar Grant, the 22-year-old San Francisco Bay Area man whose fatal 2009 shooting by Oakland BART police sparked outrage and protests against police brutality.

Diaz stars as Sophina, Grant’s girlfriend and the mother of his daughter.

The Weinstein Co. bought the film, the directorial debut by Ryan Coogler, at the Sundance Film Festival for $2 million even before it won the fest’s U.S. Grand Jury Prize and Audience Award.

Fruitvale Station is set for release on July 12.
