At the start, four women are on a inflatable boat. (One of them is in the water.) Then a shark attack the woman in the water, then attacks and kills the others.
Near the end a pack of sharks attack the people at the beach.
A girl is is relaxing on a boating dock, then a shark leaps out and grabs her feet and pulls her in and is killed (off-screen.)
When a shark bangs into a boat, a man trips and falls into an arrow. Which stabs into his shoulder.
A couple are in the water, the woman is attacked and then the man is attacked.
