PLOT
In rural Comfort, Texas, the strict protestant Horizon Bible church community holds its annual, pretty strictly supervised summer camp, with mandatory prayer sessions, for fraternizing teens from all over the States. The day before their departure, storm weather is announced, the busses even ride early to keep ahead, but the wind makes a river rise too fast: the busses are caught, everybody must run on foot. As TV reporters see from their helicopter, the rising water is too fast for one bus after choosing the wrong way, children and staff must climb in trees but can't cling on very long.
