Brothers who's parents are missing, a guy gives one of the brothers a pocket watch on a train, that brother then goes to work at a hotel, which he finds a secret room in an elevator there. The people in the town say there are people that have gone missing and it only happens at night. The older brother (that works at the hotel) goes outside and hears his brother screaming and follows the sound and he sees his younger brother get dragged into the ground. And then all I can remember is the older brother goes back to the elevator, grabs some sort of map. Underground where he later finds his brother, there's people digging looking for some sort of egyptian tomb or something. And the people that kidnapped (drug the little bro) underground found the tomb and they made the little bro go in and get what they needed (whatever that was) and the tomb started filling up with water and his older brother later found him as he was taking his last breaths and then all I know is at the end the dad starts talking to himself in a room by a casket/crate and the mom (his wife) is inside wrapped like a mummy alive, struggling. And that's honestly all I remember...Thanks!
