The video tutorial explains tree recursion, focusing on making multiple calls within a single recursive call. It covers the concept of tracing trees and call stacks, demonstrating how recursive calls are executed and how stack memory is managed. The tutorial provides a practical exercise to reinforce understanding and concludes with a summary of key points.
