A quick recap of Primeval's first two seasons. A team in Britain, based in London, have discovered Anomalies, rips in space/time. Creatures can and have come through; usually prehistoric, but some from Earth's future as well. The team identifies and contains these Incursions.
The team currently consists of Nick Cutter, a evolutionary scientist, Connor Temple, his former student and now the project's go-to tech guy, Abby Maitland, a zoologist specialising in lizards and animal behaviour, Jenny Lewis, their PR manager, and James Lester, their long-suffering Home Office boss. Former members of the team are Stephen Hart, Nick's right hand man, and Captain Tom Ryan, their military minder. Both were killed, separately, in Creature attacks. Their main opponent is Helen Cutter, Nick's wife. She left him to explore the Anomalies and currently has some rather apocalyptic views on evolution.
Tom Ryan's death was relatively early on in what's known as the ARC project – Anomaly Research Centre – but Stephen's death is very fresh.
( So. On to Season Three. )
