Movie Troubled Mission (2008)

A spaceship shaped like a human enclave faces Liberty Island. Its crew (small, intelligent and unemotion beings) are looking for an orb sent from its planet to extract the salt of the ocean, which will destroy the earth. The orb is in possession of Josh, the fifth-grade son of a single mother whose vehicle attacks an ambulance spaceship and cripples its power supply. The crew has 48 hours to recover the orb, throw it into the Atlantic Ocean, and leave Earth. Over the course of two days, the ship’s crew experiences chaos and emotion in New York. Being the giants of the Earth – Josh and his mother – have anything to teach these brave aliens? Meanwhile, Mutiny is going on and the police are closing in.
