Sees trouble, grabs a hat and gets out (7)
I believe the answer is:
escapes
'gets out' is the definition.
(I've seen this in another clue)
'sees trouble grabs a hat' is the wordplay.
'trouble' indicates anagramming the letters.
'grabs' means one lot of letters goes inside another.
'a hat' becomes 'cap' (cap is a type of hat).
'sees' is an anagram of 'eses'.
'eses' going around 'cap' is 'ESCAPES'.
'and' is the link.
(Other definitions for escapes that I've seen before include "Breaks free" , "Flights" , "Breaks out, gets away" , "Evades" , "Breaks loose" .)
