This tale is about young Ludvik (Robert Nespor) an erstwhile, budding scientist whose practical sense leads him to experiment before his common sense has figured out the results. Due to that unfortunate pattern, he variously floods the bathroom while working on displacement of volume and weight in water, he shatters the harvest pumpkins but not the law of gravity, and now he is eyeing the neighbor's rabbits for an electricity experiment. While the rabbits remain safe for awhile, Ludvik's parents wish he would follow in their more traditional footsteps and dedicate himself to music. Instead, Ludvik has learned that the proper mixture of a certain carbide and water can be explosive, and while he works on that technique, a friend tips off the physics teacher about these potentially disastrous plans.
A quarter century after the release of the original film, this sequel brings us a drama about platonic love, life retrospective and memories. Former schoolmates meet again in the mountains and it turns out they have not changed much. Even though so many years have passed, we can still see the souls of boys and girls we know from the teenage comedy Snowdrops and Aces; kids who participated in that legendary skiing course. Its nostalgic humour gives the film a bitter-sweet touch. Thawing Out follows the lives of the main heroes during a period of great changes. How did they manage to escape the traps and what scars have they suffered? Where did they want to go, how far have they got and what is still in front of them?
