READ MORE: Sundance 2016 Competition Lineup Unveiled, Over 40% Directed by Women

The Sundance Film Festival is about to start up, and Indiewire has an exclusive clip for "Mammal," which looks to be a fierce competitor in this year's World Drama Competition. The intimate character drama is a co-production between Ireland, Luxembourg and the Netherlands and stars Academy Award nominee Rachel Griffiths ("Muriel's Wedding," "Six Feet Under").

Griffiths plays Margaret, a divorced woman in Dublin recovering from the recent death of her teenaged son. She finds solace at a local swimming pool, where she soon meets Joe (Barry Keoghan), a homeless youth at odds with a local gang. Margaret lets him stay at her home, where the two find themselves to be kindred spirits in their isolation from the rest of the world. However, their bond is threatened when Margeret's violent ex-husband, Matt (Michael McElhatton), returns into her life.

"Mammal" will be having its world premiere at Sundance, which will be running this year from January 21-31. Check out the exclusive clip above.
