The film stars Penelope Sangiorgi, who was the lead actress in the trio's last film Sound of Silence, alongside Christopher Jones, David Ajayi, and Francesca Vettori.
The Grieving revolves around Mia, a mourning daughter, who attempts to lay her father to rest, only to uncover the dangerous demons he was battling. As she struggles to make sense of a world without him, grief gives way to a chilling truth.
"I'm thrilled to add The Grieving to the Vaneast slate. T3 are visionary filmmakers who've delivered a film that's as terrifying as it is conceptually bold," said Vaneast founder Gasher.
"We're incredibly excited to be launching The Grieving with Vaneast Pictures in the international space, a company that share our passion for bold, emotionally resonant genre films," said T3 Directors.
"Bringing 'the other world' into this one has always been at the heart of this project. As with our previous work, we aim not only to terrify, but to explore something deeply human -- the invisible threads that connect us all to loss, memory, and what lies beyond," they added
The Grieving is the second film from T3. Their last film Sound of Silence premiered on Tubi in the U.S. and was repped by XYZ for both domestic and international sales.
Both films are produced by the T3 Directors, Raffaele Rinaldi and Riccardo Scalva.
