A weekend trip to the zoo turns into a living nightmare when six-year-old Noah, who suffers from a critical heart condition, accidentally falls into the black bear exhibit. His father, Frank, who has spent years distracted by work and phones, jumps in without a second thought. Now, trapped in the enclosure with a lethal predator and a son whose heart is failing by the second, Frank must fight for every breath—both his own and his son’s. As the clock ticks down on Noah’s condition and the bears close in, Frank discovers that the most dangerous thing in the enclosure isn’t the bear—it’s the realization of how much time he’s already wasted. A brutal, breathless journey of survival, sacrifice, and a father’s desperate fight to make things right.
