The plot centres on the titular Rescue Force, a team of rescue workers equipped with high-tech equipment designed to stop extreme natural disasters. It carries a Rescue Police vibe in that their equipment is designed primarily for rescue efforts, not to fight evil. Despite this, the show slowly crept towards evil-fighting with antagonists Neo Terror artificially creating extreme disasters and sending Mooks to interfere with the rescue efforts.

Hikaru has joined Rescue Force that protects people from disasters, with his code name being R1. However, everyone else calls Hikaru "the apprentice". A fire broke out on an artificial island. It is a super-disaster caused by Maare, San, and Sica of the evil faction Neo Terror. Rescue Force members equip with powered-up suits and carry out rescue operations, but the fire does not subside. R1 boarded the Rescue Striker.
