Primal

Primal (2010) is an Australian horror film you can watch online on iFILM. Director Josh Reed takes a group of friends out to the bush to study a remote ancient rock painting with an anthropology student — and then makes it impossible to leave.

After an after-dark swim in a waterhole, Mel (Krew Boylan) comes out wrong. Feverish, unfocused, and hunting. The others figure it out too late, and discover that she won't be the only one to change. The petroglyphs they drove hours to photograph turn out to explain exactly what's happening. Low-budget, tight, and genuinely unsettling — the horror here comes from eroding trust and nowhere to run, not from effects. Stream Primal online on iFILM.
