Keroppi and his crew are just trying to enjoy a day at the playground when a group of bullies shows up to spoil the fun. Rather than back down, the friends challenge their harassers to a baseball match, stakes high and pride on the line. What starts as a simple game quickly becomes something bigger when tension runs through the team. Junk, a key player, finds himself at odds with the others over strategy and tempers flare. He walks away from the squad right when they need him most, leaving the group scrambling to fill the gap. With their strongest player gone and the competition heating up, Keroppi faces a choice: rally his remaining friends and find a way to win without him, or accept defeat and let the bullies have the last laugh. The match becomes about more than just baseball. It's about friendship tested under pressure and whether a fractured team can come together when it counts most.
