Phobos Rising - S4.E24

For 30 years there has been a fragile truce between the Free Alliance and the Coalition of Middle-Eastern and Pacific States, both on Earth and on Mars. Both groups mine triradium, a super-powerful radioactive mineral that can be used for both power and illegally for weapons. When a giant explosion appears to consume the Earth and sends a giant shock-wave towards Mars, the soldiers at the Free Alliance base on the Red Planet wonder if the truce has come to an end. Cut off from Earth for 12 hours as Mars rotates, Colonel Samantha Elliot (Barbara Eve Harris) believes someone from the Coalition has been smuggling triradium. With communications temporarily out of order and a Coalition drone approaching the Alliance base, Elliot prepares to launch a preemptive strike. Major James Bowen (Adam Baldwin), who has grown fond of Major Dara Talif (Joan Chen), the Coalition liaison officer at the base, disagrees with Elliot.
