scripts and loglines are written in the present tense because things happen on screen right-now.
Also, stories are about what the lead character must do. Your logline attempt is just a set-up, the story would be about what happens after he is kidnapped.
Here is an example: (Yours would be different)
-----
"When he is left for dead in a locked room, a kidnapped billionaire must use his childhood skills as a street magician to break from his prison and get revenge on his abductors."

Great comment by Richiev.
Feel free to check out the 'Formula' tab up top for more information on how best to structure loglines.
Take a look at the wonderful resources for writing loglines that this site has to offer.
Yours is written in past tense and doesn't work to generate a hook. Write what must be done, why and what will not be achieved or lost if such act is not done.
