A space shuttle craft drops a load of dust as it comes in for a landing. The dust settles on the Burton farm where a farmer and his young daughter live. The space staff is alarmed and sends a crew in protective suits to clean it up, but it is Mitch and Griff who have to handle the dirty work when Ryan is infected.
It was the wrong day for a picnic! Mitch and Ryan head for the oil rig abandoned after a strange accident and spot a drifting yacht. Searching it they find a terrified young woman who says her host was pulled off the yacht by a weird sea monster. They have to abandon the yacht and use a rubber life raft to reach the oil rig where the gelatinous green stuff catches them.
