18-year-old Liam visited his Grandpa’s grave to say goodbye before moving out of town due to his father’s gambling debts. As he scraped moss off the tombstone, he discovered coordinates etched into the marble. Curious, Liam followed the trail to a railway station cloakroom, where he uncovered a locker containing $150,000 and a diary from his Grandpa.

The diary revealed that Liam’s Grandpa had saved the money for years to fulfill Liam’s dream of becoming a flight engineer. It also exposed the dark truth: Liam’s father, David, had stolen from his own father’s savings to fuel his gambling addiction. Despite the betrayal, Robert had worked multiple jobs to rebuild the lost savings for his grandson.

Liam confronted his father, offering to help with the mortgage under two conditions: David must quit gambling and pay the mortgage immediately. David agreed, but when he attempted to deposit the money, he discovered it was fake. Liam had tricked him, proving his father hadn’t changed.

Leaving his father behind, Liam took his real inheritance and fulfilled his dream, walking into the Aviation Academy with the promise to make his Grandpa proud.
