The game revolves around the Elite Beat Agents, a group of government employees who specialize in helping people. The story varies on the level, with some levels being not very serious (such as helping a babysitter ask out her friend), while some are (such as helping a former baseball player defeat a lava golem). The Agents the player plays as depends on the difficulty. On Breezin' (Easy), the playable agent is Agent Spin. On Cruisn' (Medium), the playable agent is Agent J. Beating Cruisn' unlocks Sweatin', or hard. On Sweatin', the playable agent is Agent Chieftain. For Agents Spin, J, and Chieftan, their back-up dancers are Agent Derek and Agent Morris. Beating Sweatin' unlocks a super hard mode called Hard Rock!, where the playable agents are the Elite Beat Divas. The player plays as Starr, while the back-up dancers are Missy and Foxx.
