As a first-year bonding exercise, a group of Thai university students descend upon a holiday camp in the jungle. Disaster strikes en route to the camp when a rickety bridge collapses under their rented bus, drowning many. Confusion reigns as pic fails to decide whether it's a ghost story or a slasher yarn. Nor does the story take much time to differentiate between characters, settling for quick introductions before killing students one by one. Some of the deaths are outrageously inventive, but the finale is just plain lazy. Helming is perfunctory, but urgent cutting maintains a kind of nonsensical momentum. Rough tech credits do the job, but an insistent soundtrack propels this film into hysteria of an unintended kind.
