ies, who have failed to meet their cruel parents' often impossible expectations and have been returned, only to be spared a ruthless end by the criminal tasked with their disposal. A man who has grown a conscience and acts as their guardian. Action and thrills are plenty, as the matured defects, now in their 20's, take on the crime syndicate who created them and seek revenge against their heartless parents. The only downside is a dash of the obligatory woke nonsense. In summary, a somewhat original, wholly watchable crime action thriller from South Korea. Worth a look.
