The wake up in a mysterious room inciting incident has been used many times only it presents a problem if used incorrectly.

According to this logline the MC wakes up in a room on frame one which means this is the normal day to day of his life in this story. Whilst an un usual normality by most standards it is the established “norm” for the MC. As such you need a secondary inciting incident after he wakes up to motivate him to take action or else waking up becomes a vague inciting incident because we don’t know what changed in his life as a result.

Consider “The Cube” a similar premise without the doctors the MCs wake up in a room – the norm, then one of them is gruesomely killed – the inciting incident, they must now take action to save their lives.

Secondly making the MC an amnesiac can help in the writing but doesn’t work well as a character description. If he is an amnesiac how can he know he is an amnesiac unless he is told he is?

This means after waking up he can’t tell he is an amnesiac on his own.

Lastly the goal in the logline – “…must uncover why sinister doctors are performing grisly operations on him.” is not a strong enough goal. Once he discovers why they are doing the operations then what? He will simply willingly comply as all he needed was for them to give him a good enough reason?

I think best to specify that he must stop them from carrying out any further operations as appose to just finding out why they are doing so.

Hope this helps.
