Harm and Mac try to help a marine who drives his tank over his commands tent during an exercise. He claims he was distracted because his ex-wife has sole custody of their son, and feared for his son's safety due to his ex's unproven drug habit
Review
This episode is a very fine performance with the main character/plot storyline, good tv guest role, and if nothing else there are two main reasons this is worth seeing - 1. the tank scenes, nothing better than taking your child and then using a tank to negotiate your rights and 2. the Quantum Leap convention that suddenly occurs half way through - very nice nod to the show creator's previous work.
