Here's a plot summary, thanks to Craig Fuqua. I don't think we're too worried about spoilers.
Race is away and Jonny is bored on the island while his dad works on his anti-laser equipment. Jonny sees paratroopers landing on the island, so he runs up the "secret cave" which leads to a trap door in the lab. While trying to leave, Jonny trips and falls on the floor as the invaders burst in. The Quests are held hostage and the leader arrives. Then Race pops in through the trap door, backed by government troops and turns the tables. At supper, Race explains that Jonny fell on the trouble signal button on the floor.
