The CW has previewed the upcoming midseason premieres for three of its Arrowverse shows. Supergirl, The Flash and Arrow are all set to return in January with new episodes and all of the heroes are struggling in their own ways. The network has just released the synopses for the upcoming episodes and the DC heroes are going to have a lot on their plates when they return.

Warning: spoilers ahead for Supergirl, The Flash and Arrow. If you're not caught up on all of the Arrowverse shows, these plot descriptions for the upcoming episodes do contain spoilers. So get caught up before you read what's coming up next. First up is Supergirl, which returns on Monday, January 15 in the episode Legion of Superheroes. Here's the official synopsis for the episode.

"Struggling to heal from her injuries inflicted by Reign, Supergirl remains in a dreamlike state, unable to be reached. Mon-El recruits one of the Legion members, Brainiac-5 (Defiance's Jesse Rath), to try to bring her back. Meanwhile, Reign continues her rampage on the city so the DEO teams up with the Legion of Superheroes to try to stop her."

Next up is The Flash, which sees Barry Allen return in a very compromising position in the episode The Trial of the Flash on Tuesday, January 16. In the episode, "As Barry's trial for the murder of Clifford DeVoe begins, Iris and Joe must decide how far they are willing to go to keep Barry out of prison." It sounds like this is going to turn The Flash into something of a courtroom drama for at least a week. Maybe Barry will end up in prison for a bit? Like father like son.

Finally, Arrow returns with the episode Divided on Thursday, January 18. Oliver Queen has seen better days, but his confidence hasn't wavered any, even though half of his team is gone. It's now up to him, Felicity and Diggle to stop a growing threat. That is, until he finds an "unlikely ally". Here's the full synopsis.

"Despite losing half his team, Oliver remains confident that he, Felicity and Diggle can stop Cayden James and Black Siren However, when he discovers one of Cayden's secrets, he decides to team up with an unlikely ally. Meanwhile, Dinah spends time with Vince."

Noticeably absent from this lineup is DC's Legends of Tomorrow. The series doesn't actually return until February 12 from its hiatus, replacing Supergirl in the Monday time slot it occupies for a short while. So it's likely that The CW will release a synopsis for the Legends of Tomorrow midseason premiere in January, which is why it wasn't included in this Arrowverse preview, via TV Line. Even so, it sounds like there's going to be plenty of Arrowverse action to go around in the new year with Supergirl, The Flash and Arrow all in pretty dramatic situations.
