Episode 4

An anomaly opens underwater, dragging a teenage boy into a flooded drain. Professor Nick Cutter and the team launch a frantic search that leads them from the drain to a nearby canal.

Jenny narrowly escapes a grizzly end when the boat she is in comes under attack by a shark, but a strange discovery during the creature’s post-mortem suggests it may not have come from the past. The creature’s secret weapon is a giant proboscis that shoots from its jaws to trap its prey, clear evidence of an unusual evolutionary development. It is from the future.

The team are confronted by some sinister creatures from the future – strong and intelligent, the mermaid-like beings are a formidable bunch, giving the team their toughest challenge yet.

Stephen Hart (is convinced that there must be a second shark in the water and that’s what killed the teenage boy, but Cutter isn’t convinced. He thinks there is a different creature out there and he feels certain they are looking for it in the wrong place. Cutter disobeys the orders from James Lester and follows his hunch.

With the help of Connor Temple and Abby Maitland he records some strange “singing” sounds coming from below the water. They then play them back, hoping to lure the creature to them. The plan works a little too well when a creature jumps out of the water and grabs Abby, dragging her beneath the water.
