Bones S2 E9: Aliens in a Spaceship
The team investigate the murder of two kidnapped teenage twin boys. The boys were placed in a spaceship-like capsule and buried alive underground. Soon, Brennan and Hodgins find themselves victims of the "Grave Digger", and Booth frantically searches for them as they slowly run out of oxygen underground. The case has no conclusion, and it is unsure whether it will ever be solved.
