This is a prison escape movie like Alcatraz, escape plan. But made illogically. We do not want any reason why they came in unless that's going to affect the story in anyway. So at start itself this movie got behind.

Keys with wood is just not possible. Argument closed. None of the characters are interesting. This movie goes like it's a drama. Protagonist will win anyway.

He just has 2 keys, wooden keys, and opens any and every door. Later he says he made 39 keys. When did he make it?

In a dark silent night, you can hear someone cough and give signal but not 2 people running, opening locks, opening steel jails, closing doors. Weird. Nothing more to say.
