Multiple people are "killed" and attacked by a demonic shark. Alot of the deaths are really cheap and bland.
At the start of the film a nun stabs a woman repeatedly, lots of blood spills, and she drags her corpse into the water. A similar scene is shown later near the ending where she kills another woman like before, but unexpectedly the victim from before rises from the water and drags the nun into the water.
A woman becomes possesed and bites a man by the neck. (He presumably dies)
