So this started out as a family show, with some comedy sprinkled in! Yong Nam (Jo Jung Suk) is an unemployed man who rock climbs. He is of course the family black sheep disgrace, but has to put up appearances at his mother's 70th Birthday. The celebration reunites him with Eui Joo (Im Yoon Ah) a climbing companion from his student days, a girl he had previously asked out and been rejected by! How backward.

Then suddenly the movie morphs into a terrorism play where an employee who has been fired and his patents stolen by a company, takes revenge by releasing a bunch of poison gas at the company, gas that spreads outwards and upwards, killing all in its path. I'm not gonna lie, at this point I was worried this was going to turn into another Korean Zombie movie, because, well ... Korean Zombie movies? But it didn't! It's just poison gas. Now the entire city and our intrepid family (among others) is at risk. What follows is a taut, tight, exciting action thriller which showcases both the main leads ingenuity, resourcefulness, partnership and most of all, the lengths people will go through to survive. Sprinkle in some drones and good music and now the climbing scenes are both exciting AND poetic.

Now the rock climbing is pretty tame. I'm a fan of mountaineering movies so this wasn't the same caliber as Free Solo, The Summit (K2), Nanga Parbat, Touching The Void, The Wildest Dream (George Mallory) or even the cheesy Vertical Limit. But we did manage to see some examples of technical climbing including an exciting drone assisted improvised zip-line. Nice!

This review can best be summarized in the words of my almost teenage child - "I nearly had a heart attack Mommy! I'm out of breath and I wasn't even there." I guess this means we both enjoyed the laughter and thrills this had to offer!
