The inciting incident (discovering the special power) of the main character (the Psychiatrist) happens to the ally (the patient) not the main character. This is a problem as the inciting incident needs to happen to the MC and motivate him to take action.
Why not as DPG suggested make the one who discovers the powers the one who possesses them this way they would be compelled to do something with them. Other wise the main action described in the logline is to convince the psychiatrist.
If not that then let the psychiatrist discover his own powers and need to deal with them.
Hope this helps.
