in a pickle

in Dutch in a tight spot in hot water on the hot seat on-the-spot out on a limb up the creek

Catch-22 Hobson's choice between Scylla and Charybdis between a rock and a hard place between the hammer and the anvil between two fires cornered in a dilemma in a predicament in the middle no choice sitting on a powder keg

in a jam in a mess in an awkward position without choices
