Watch Sea Trial (1976) Official Trailer

Lu Dahai and his shipbuilding team want the 10,000-ton ocean freighter "The East" to be given a sea trial. But the ship is made with domestic parts, and Chen Zongjie, a leader of the Party Committee of the Bureau of Foreign Transport, believes that the quality is not sufficient, and orders that the parts be replaced with imported ones before the sea trial takes place. In the end, the sea trial not only sets a successful new record, but also rescues a Taiwanese fishing boat in distress.
