Marvel fans who have been watching Agents of SHIELD and saw the recent hit movie Captain America: The Winter Soldier are in for an explosive surprise, as per the synopsis of the series' finale.
The show, which superbly connected itself to Captain America 2, has generated enough interest among viewers and fans to make its season 1 finale episode an eagerly-awaited one.
Here is the synopsis for the Season One Finale of Marvel's Agents of SHIELD:
"Dark secrets are revealed as Coulson and his team put everything on the line to stop Garrett and the forces of Hydra, on the explosive season finale of "Marvel's Agents of S.H.I.E.L.D., Tuesday, May 13 (8:00-9:00 p.m., ET) on the ABC Television Network."
Everything that SHIELD ever knew and trusted came crashing down as the organisation known as HYDRA revealed themselves, reports Fansided.
"HYDRA revealed itself as infiltrating SHIELD at the highest levels of operation. One of those traitors is right under the nose of Agent Phil Coulson," states the report.
Now, Skye (Chloe Bennet) has gone and Ward (Brett Dalton) needs her in order to decode the hard drive that contains all of SHIELD's deepest, darkest secrets.
It remains to be seen what lengths Ward will go to in order to get what he wants.
The build up to the finale might start with tonight's episode as there are only three more episodes left in the season.
Marvel's Agents of S.H.I.E.L.D. airs on Tuesday nights at 8:00 pm on ABC.
