Sumerian Pictures' new trailer for Josephine is a tense experience, teasing a chilling mystery around one question: What did Josephine (newcomer Mason Reeves) see happen in the park? But the film, of course, digs even further.

This Sundance Grand Jury and Audience Award-winner from writer and director Beth de Araújo (Soft & Quiet) is based on her own life experiences. Channing Tatum and Gemma Chan lead the film as parents of eight-year-old Josephine, who witnesses a crime in San Francisco's Golden Gate Park. How can her parents help her process it?

Mashable entertainment editor Kristy Puchko called Josephine "easily the most buzzed-about title out of Sundance."

"Not a tear-jerker but a nuanced family drama that's ripe in emotional intelligence and thought-provoking sequences, Josephine is a hard watch and a must-see," she writes in her Sundance round-up.

The cast also includes Philip Ettinger, Syra McCarthy, and Eleanore Pienta.

Josephine hits cinemas Nov. 20.
