In this episode of rescue soldiers, Nagare and Shou go to the public unveiling of the firefighting robot Big Douser, which Nagare had a hand in developing. Meanwhile, Pierre attempts to scavenge some sort of plan together and decides to target the robot for his own nefarious deeds.
Do you remember episode 28? Yeah, this episode is more or less the companion piece to that one.
