The cold light of the fluorescent lamps cast grayish hues over Terminal D of Otopeni Airport. Officer Andre scanned the crowd with the vigilance born of years of experience. Beside him walked Luna, an imposing German Shepherd with a shiny coat and intelligent eyes. For three years, they had been an unbreakable team. In all that time, Luna had never made a mistake.

Andrei moved his gaze from face to face, watching gestures, movements, reactions. It was a game he knew by heart.

But that night, something changed.

Luna stopped abruptly. Her ears perked up, tail stiffened, and her gaze locked onto a woman pushing a stroller with a baby wrapped in a light blue blanket. The dog’s nostrils flared, sniffing the air with an unusual intensity. Then, without warning, a low and threatening growl rumbled from her throat.

Andrei sensed the shift immediately. The air seemed to thicken around them, and the terminal noise faded like in a dream. The woman — a thin brunette, eyes swollen with fatigue, pale-faced — clutched the stroller handle in desperation and stammered:

— Take the dog away from my baby!

But Luna didn’t obey. For the first time in her career, she didn’t respond to her handler’s command. With astonishing speed, she lunged at the stroller, her heavy paws slamming into the plastic frame. The blue blanket slipped away, and what came into view froze everyone in place.

Under the baby blanket, there was no infant. Instead, a thermal bag lay nestled between the pillows, carefully sealed. Labels in Russian and Chinese were stuck on it, marked with biological hazard symbols. Shiny containers could be seen inside, and a sharp chemical odor emanated from them.

Andrei reacted instantly. He grabbed the woman by the arm and pulled her aside, while Luna stood still, eyes locked on the stroller’s contents. Another officer rushed off to call the anti-terrorist team.
