Shark

Captain Peter Van Damm finds himself passed over for the rank of admiral and retires. The Company makes him an offer he can't refuse: command of his old Triton sub, Oregon, and a large sum of money if he will take his old sub out on a shakedown cruise with an untried heavy water power plant. He ends up with a sub half full of women, the other half consists of retired sailors and marines, and everyone trying to sink the sub.
