"Struggling" is a strange description for the MC as a secret agent. Struggling normally implies financially in the context of a secret agent that seams unrelated, what is he struggling with?
Is there a different character description you can use? A description that could imply a character flaw for the MC to overcome in their inner journey?
Waking up in the teacher's body sounds like the inciting incident for the MC as this has never happened to him before. In this case no need to mention him getting shot as that is a perfectly normal thing for secrete agents. Save words in the logline and get strait to the inciting incident in the beginning of the log line.
"...they'll be forced to go on the run..." sounds like a passive character better to have them go up against the bad guys by choice make the MC an active one in pursuit of the bad guys. On that note give the MC a clear goal such as: put the bad guy in jail, get back his own body, etc...
Hope this helps.
