From Lindsay Zier-Vogel of CTV:

• David Paetkau promises an intense ‘Flashpoint’ finale episode
  Season 4 started with Ed Lane (Hugh Dillon) in the hospital, recovering from a gunshot wound…and things have only gotten more intense. Later on in the season, he was held hostage, and so was Spike (Sergio Di Zio), and Parker (Enrico Colantoni) (on top of a scoreboard, no less!). And no one was spared – Sam’s (David Paetkau) sister was held hostage and in the second-to-the-last episode, Jules (Amy Jo Johnson) was hit with shrapnel. Read more.

From Rob Salem of Toronto.com:

• CBS missed the point of Flashpoint
  Flashpoint don’t get no respect. At least, not from CBS, its former American network home, which followed three seasons of tacit neglect by unceremoniously dumping the show in the middle of its fourth, to be picked up by ION Television, a sad little U.S. cable net that airs more infomercials than it does actual shows.

As Parker (Enrico Colantoni) is confronted with orders to resign, Team One responds to a bio-terror call at a laboratory – forcing Sam (David Paetkau) to make a decision that puts Jules’ (Amy Jo Johnson) life at risk. Guest stars include David Alplay (THE TUDORS) and Anjali Jay (Blind Dating). Victor Garber (Titanic) also returns reprising his role as psychologist Dr. Toth.

When Sam’s (David Paetkau) sister Natalie (Rachel Skarsten, Jack Brooks: Monster Slayer), is threatened, Spike steps up to protect her and winds up in a trap that forces him to square off against his own team.
