I Shouldn't Be Alive (2005)

S2E5 Blood in the Water

Five adventurers on a boat safari become trapped in the dangerous waters of the Zambezi River after their vessel sinks, thanks to an aggressive hippo. Three of them find themselves marooned on a submerged sandbar in the river, while the other just manages to reach the safety of the shore. With Africa’s lethal wildlife lurking nearby, the situation becomes increasingly perilous for all.
