Ensign Kim has been given the chance to command Voyager during the 'night' shift (there's no night or day in space!). However, this shirt is anything but dull in this episode. It all begins with the ship receiving a distress call. When Harry and the Doctor land on a craptastic planet, they find that the call is NOT coming from a living being but a machine that THINKS it's alive! Naturally the Doctor is excited, as he thinks he'll have some new mechanical friend. However, when they bring it aboard they learn the truth--it's a type of smart WEAPON. Way to go, Harry!
This is a decent episode. It also gives Robert Picardo a chance to act a bit outside his normal range as he's soon taken over by the weapon and it makes him act a tad grumpy, to put it mildly. Original and worth seeing.
