Abraham (David Bradley) and Fet (Kevin Durand) will take on the Master in the upcoming episode of FX's horror drama series "The Strain."

In "The Born," Hollywood Hills reports that the two will plan a direct attack on the Master with Fitzwilliam's (Roger Cross) help. Eldritch Palmer's (Jonathan Hyde) one-time bodyguard apparently gave them useful information on where to find the villain and how to kill him.

Will his tip help the two put an end to the Master's evil plans, or will it endanger their lives? Abe and Fet may find that they are wrong to rely on someone as deceitful as Fitzwilliam, especially with the arrival of a mysterious new player. Who is this man and what is he after? Is he another one of Master's minions, or an ally of some sort?

Meanwhile, someone will pay a surprise visit on Dutch (Ruta Gedmintas). Eph (Corey Stoll) will find himself rushing back to New York City to track down the person responsible to the death of his friend.

Last episode, Eph's work in NYC was done as Councilwoman Feraldo (Samantha Mathis) had started purging the city of vampires. He was heading to Washington D.C. where we would meet up with Rob Bradley (Tom Ellis), the doctor he was in contact with to mass produce the bioweapon. There, he worked with Leigh Thomas (Nadia Bowers) who could help him in the production process. Everything appeared to be going well, until the Stoneheart Group sent an assassin to kill Leigh.

In New York, Nora (Mia Maestro) and Kelly (Natalie Brown) were both engaged in fierce battle over Zach. Eph's son would have to face a difficult choice soon. Whom would he choose between the two — his parent or the person he had come to look up to as his own mother?

Meanwhile, Mr. Quinlan (Rupert Penry-Jones) arrived in the city and met up with the Ancients. He promised them that he would take down the Master, but he needed all the help he could get. As for his sworn enemy, he had finally chosen a successor. Gabriel Bolivar (Jack Kesy) received the Master's blessings to become to most powerful dark vampire known to humanity.

"The Strain" airs Sunday at 10 p.m. EST on FX.
