[TOMT][MOVIE] Bunch of teens get killed by a guy, one girl cut in half by a circular saw blade while climbing a ladder

Think it’s a pretty standard horror movie. Teens get killed by some dude in a deserted area/ small ghost town. Arid area, empty broken houses. Towards the finale, one girl gets cut in half by this circular saw blade while she was trying to climb a ladder of sorts in a tunnel .

Afterwards, there’s this dude driving and a girl on the right. She or he stabs the other one in the leg with a nail . I saw this when i was very young from a rip CD i got along with Eden Lake. Might be early 2000’s but not sure.

It’s all i remember that marked me as a kid. Thanks in advance for anyone trying!
