They throw a dog overboard.
Jesus, I saw this film on TV when I was 4 years old - don't think my parents thought that one through.
The people in the lifeboat decide the kid's dog has got to go. The kid begs and cries and holds onto the dogs neck - and then he gets tossed overboard.
I went into total kiddie hysterics. My dad improvised "Dog's are great swimmers. They put him in the water because they know he can swim back to land."
Hell, I believed that one into my teens.
Haven't seen it since then, but I intend to revisit it. At four years old, it was as intense as heart attack.
