Aussie feature Undertow has begun pre-production, with shooting to begin in the middle of next month in Geelong and along the Surf Coast.
The thriller will see writer-director Miranda Nation reunite with producer Lyn Norfor, of Emerald Productions, and DP Bonnie Elliott (Spear).
The trio previously worked together on Springboard short Perception, which won the Sydney Film Festival's Dendy Award in 2013.
Porchlight's Liz Watts (Animal Kingdom, Lore) is executive producing.
The film, set against the football culture of Geelong, tells the story of Claire, a woman struggling to accept the loss of her baby who becomes suspicious of her husband's relationship with a feisty young woman, Angie.
When she discovers Angie is pregnant, Claire develops an increasingly irrational obsession with the teenager.
The project received development funding from Film Victoria last year. The Melbourne International Film Festival Premiere Fund is also backing, with a MIFF 2018 premiere likely.
Nation, who completed a director's attachment on Kasimir Burgess' 2014 feature Fell and Cate Shortland's upcoming Berlin Syndrome, is repped by HLA Management.
