This improv game is in the following improv game categories:
4 players, one leaves the room. Pick a means of transportation, and an object. The idea is that player number 4 needs to guess the means of transportation, and then use the object to hijack the others. Finally pick a goal for the hijacker to achieve.
The players need to provide hints to the hijacker, but they cannot explicitly tell the hijacker what to do, with what or why. Also known as Rebel without a Clue.
