A British expedition's successful attempt to climb the Trango Tower in the Karakorum Range of the Himalaya's in 1976. The climber Martin Boysen relates the events of the team's first failed attempt to ascend the Tower in 1975. This is followed by footage filmed on the 1976 expedition and the climbers, Martin Boysen, Joe Brown, Mo Anthoine and Malcolm Howells, narrate their experience of the 1976 attempt. The team is seen arriving in the region, hiring porters and trekking over hazardous terrain to reach their base camp. The first attempt to climb the Tower on this occasion is thwarted by bad weather, but the climbers return a few days later to make a successful attempt on the summit.
