Thrust into a bad situation (3)
I believe the answer is:
jam
This clue is a double definition.
'thrust' is the first definition.
(thesaurus)
'a bad situation' is the second definition.
(I've seen this in another clue)
'into' is the link.
(Other definitions for jam that I've seen before include "Preserve; pack tightly" , "awful traffic" , "Preserve - predicament" , "Sweet stuff for bread - stuff it in" , "Block signals" .)
