by Max
(Chicago, Illinois, USA)

In this film, six or so police or military agents go for training to an island and one by one start dying. The island is supposed to be deserted and for training purposes.

One guy gets liquid nitrogen on him and "breaks", one girl starts smoking a cig and starts to get burned from the inside out, one guy's blood is drained and written with all over the wall in numbers.
