When two wannabe American Pickers accidentally release a demon from the strange storage unit they just won, they must track down the eccentric billionaire who reneged on the payment to discover what the creature was and how to stop the thing.

Great advice, thanks

Best to have a sing protagonist not 2.
It seems to me unnecessary to mention that they won the unit. The face is they opened a unit that they purchased.

What will happen if they don’t stop the demon ?

What is motivating the protagonist to act in this way and what will happen to him/her if they cannot fin the previous owner of the unit.?
