This film is the fifth episode of the Star Trek series, starring the original cast, but directed by William Setner, who plays Captain Kirk, and is also his directorial debut. The story describes a mysterious crazy dreamer, Seb, who occupied a distant planet, hijacked the interstellar ambassador as a hostage, and forced the Enterprise spacecraft to set off urgently to enter the unknown universe that no one has visited to find the legendary God, but who is God? The opening of this film is quite shocking, but it is a pity that it is difficult to continue to develop, so that most of the length is in the overly mysterious story framework, and can only rely on spectacular visual effects to maintain its appeal. Fortunately, the ending is slightly improved, so as not to disappoint the audience too much. The Enterprise, which is repairing at the base, accepted an urgent mission. Captain Kirk and his party were ordered to go to the planet Nimbu, which belongs to the neutral zone, to rescue the citizens of Paradise who were controlled by the traitors. The rebels hijacked the Enterprise to the center of the Milky Way to find the root cause.
