Max (Jacob Tremblay), Thor (Brady Noon) and Lucas (Keith L. Williams) are three young boys who have been playing together since they were very young. They are childhood sweethearts with a very good relationship. One day, Max received an invitation from a cool boy next door to a "kissing party". These three boys who have never touched a girl's hand decided to find out how to kiss. The three children set their research target on the neighbor's sister because she would be intimate with her boyfriend at home. The group secretly took Max's father's drone and used it to sneak into the neighbor's house. Of course, there is only one result, that is, the conspiracy was exposed. Not only that, the expensive drone was also broken, which made the three boys anxious.
