Finds the solution to how to escape? (4,3)

'finds the solution' is the definition.
Although both the answer and definition are verbs in their -s form, I don't see how one could define the other.

'how to escape?' is the wordplay.
'how' becomes 'gets' (I am not sure about this - if you are sure you should believe this answer much more).
'to escape?' becomes 'out' (as in giving someone an out).
'gets'+'out'='GETS OUT'

'to' acts as a link.

Can you help me to learn more?
