Gokaiger Goseiger 199 Hero something or other
Anyway, the keys get stolen by this guy, who was originally defeated by Goranger 35 teams ago. He has somehow been reincarnated and wants revenge on all Super Sentai.
So this takes place between episodes 16 and 17 of Gokaiger, and we see Gokai Silver at the very end of the movie. There are several guest appearances and cameos from previous Sentai members. It's fun, though I wish I knew a bit more about some of the other Sentai (aside from anything involving moving vehicles).
