In the tense crime thriller Hammer, Mark O'Brien stars as Lucas, a former boxer whose quiet life is violently upended when his brother goes missing with a dangerous amount of cash. Forced back into a world he tried to leave behind, Lucas must navigate the grim underbelly of his city, where every shadow holds a threat and trust is a rare commodity. As he follows a trail of deceit and violence, he crosses paths with a determined detective played by Will Patton and a host of unsavory characters, including those portrayed by Ben Cotton and Lara Jean Chorostecki, each with their own hidden agendas. Directed by Christian Sparkes, the film masterfully builds a claustrophobic atmosphere of paranoia and mounting dread, where every confrontation could be Lucas's last. With time running out and the pressure closing in from all sides, he must use every ounce of his strength and wit to survive a deadly game where the rules are written in blood.
