Plot
Directed by Jennifer Kaytin Robinson, the 2025 installment is a straight-up legacy sequel—not a reboot—picking up 28 years after the events of the 1997 classic. This time, five new friends cover up a deadly hit-and-run, only to receive ominous letters a year later from someone who clearly “knows what they did” and wants payback. Desperate, the group turns to the original Southport survivors—Julie James (Jennifer Love Hewitt) and Ray Bronson (Freddie Prinze Jr.)—for help outrunning the hook-wielding nightmare once more.
