How does 10 years translate to 10 seconds / relate?

What happens if he missed the 10 second deadline, it repeats? But it repeats regardless?

10 Seconds is really short

It’s too vague and very mysterious, it can work but you’ll need more context details as you go along and a more realistic opening content.

‘ Dude has been trapped for however long as indicated by rusty long chains around his leg attached to the wall, he has a minute to figure out a way out lest he risks blacking out again due to the noxious gases or some kind of mental impairment, memory wipe or something. ‘

Plus unless there’s a better end goal then just escape it’s a lot of lead up and simplicity only for an equally bitter ending, if it were like Saw with on-the-edge-of-your-seats horror and intrigue, some motives it might work but right now too little is known and unless you have more I doubt it’ll pick up enough.

Good luck nonetheless
