Tales from the Crypt (1989)

S3E12 Yellow

The general grapples with embarrassment upon discovering that the whispers of his son, the Lieutenant, being a coward are accurate. In a desperate bid to save his son's honor, he presents him with a final opportunity to prove himself through a crucial mission. Overwhelmed by fear, the Lieutenant abandons his post, leaving his fellow soldiers to face their fate against the enemy. In a fit of rage, his father condemns him to a firing squad. Luckily, the weapons are supposedly filled with blanks, or so the general claims.
